Āṉma-Viddai : Tamil text, transliteration and translation

The path of self-investigation (ātma-vicāra) that Bhagavan taught us is the direct and easy means to eradicate ego, the root and foundation of all our troubles, but there is a widespread belief that it is a very difficult path and therefore suitable only for a few spiritually mature aspirants. Even among the devotees who lived with him this was a widely held belief, as Muruganar discovered to his surprise in the following way.

One day soon after he came to Bhagavan, Muruganar was sitting in his presence, but after a while Bhagavan went outside, and while Muruganar was waiting for him to return another devotee called Viswanathan approached and whispered in a secretive manner that Bhagavan is very great, but it is not possible to know anything from him directly, and he therefore offered to introduce him to Kavyakantha Ganapati Sastri, saying that if he were to take mantra-dīkṣā (initiation in a mantra) from him he would thereby gain the clarity to understand Bhagavan’s teachings. Seeing the surprise on Muruganar’s face, Viswanathan advised him to think about it, saying he would return later. Later that day Viswanathan approached him again and asked what he had decided, but Muruganar told him that he had come only for Bhagavan’s grace, so whether he was fit to receive it or not, he was not interested in seeking anything from anyone else.

Telling this to Sadhu Om many years later, Muruganar said with a smile that Kavyakantha’s followers must then have decided that he was a hopeless case, because they never again offered him such advice. He also said that this was one of the reasons why he decided a few years later to ask Bhagavan to write this song, Āṉma-Viddai.

That is, Muruganar knew from his own experience how easy this practice of self-investigation is, but he also knew that many other devotees wrongly believed it to be very difficult, so he wanted Bhagavan to write a poem to dispel this mistaken belief and thereby reassure sincere aspirants, and hence on the 24th April 1927 he composed the pallavi (refrain) and anupallavi (sub-refrain or post-refrain) for this kīrtanam and asked Bhagavan to compose the caraṇaṅgaḷ (verses) for it. Knowing why Muruganar made this request, Bhagavan immediately composed five caraṇaṅgaḷ to explain how easy this path is and why it is so necessary.

A kīrtanam is a musical composition consisting of a pallavi, an anupallavi and one or more caraṇams, in which the pallavi expresses the central theme of the song and is therefore repeated after the anupallavi and each of the caraṇams. This kīrtanam is composed in the style of a well-known and much-loved kīrtanam from Nandaṉār Carittiram, a kathā-kāla-kṣēpam (a form of musical story-telling) that Gopalakrishna Bharati, a popular 19th century Tamil poet and musician, composed on the life of Nandanar, who is one of the most revered and loved of the sixty-three Tamil Saivite saints, whose stories are narrated in the Periya Purāṇam. Nandanar was a paṟaiyar (an outcaste or ‘untouchable’), and in Gopalakrishna’s version of his story he worked as a bonded labourer for a cruel brahmin landowner, so Gopalakrishna composed a kīrtanam in which Nandanar addresses his master and sings in the pallavi, ‘ஐயே, மெத்தக் கடினம், உமதடிமை, ஐயே, மெத்தக் கடினம்!’ (aiyē, mettak kaḍiṉam, umadaḍimai, aiyē, mettak kaḍiṉam!), ‘Ah [or sir], very hard [or difficult], [being] your slave, ah, very hard’, in which ‘ஐயே’ (aiyē) can be taken to be either an exclamation, ‘Ah’, or an address to his master, ‘Sir’. Therefore in the same style Muruganar composed the pallavi for this kīrtanam: ‘ஐயே, அதி சுலபம், ஆன்ம வித்தை, ஐயே, அதி சுலபம்!’ (aiyē, ati sulabham, āṉma-viddai, aiyē, ati sulabham), ‘Ah, extremely easy, ātma-vidyā [knowing oneself], ah, extremely easy’.

(Unfortunately, in Talks with Sri Ramana Maharshi, section 379 (1978 edition, page 344; 2006 edition, page 358), it is incorrectly recorded that Bhagavan said: “Chidambaram is the famous place of pilgrimage associated with Nandanar who sang that Atma Vidya is most difficult of attainment. Muruganar (a long-standing devotee of Sri Bhagavan) began however that Atma Vidya is the easiest of attainments”. Bhagavan of course would never have said that Nandanar ‘sang that Atma Vidya is most difficult of attainment’, because the song he was referring to was not composed by Nandana but by Gopalakrishna Bharati in his Nandaṉār Carittiram, and in that song there is no mention of ātma-vidyā. Moreover, in the same passage of Talks it is incorrectly implied that after composing the pallavi and anupallavi Muruganar ‘could not pursue the theme further and laid the first four lines composed by him before Sri Bhagavan for completion’, whereas in fact Muruganar could very well have completed the song if he had wanted to, but he did not want to, because he had composed the pallavi and anupallavi with the intention to ask Bhagavan to compose the caraṇaṅgaḷ so that he could affirm that ātma-vidyā is extremely easy.)

English translation: Ah, extremely easy, ātma-vidyā, ah, extremely easy!

Explanatory paraphrase: Ah [what a wonder], knowing oneself is [so] extremely easy, ah, [so] extremely easy!

Explanation: ‘ஆன்ம வித்தை’ (āṉma-viddai) is a Tamil form of the Sanskrit term ‘आत्मविद्या’ (ātma-vidyā), which means self-knowledge or the science of self, because विद्या (vidyā) means knowledge in a broad sense that includes science, learning, philosophy or any practical skill or art. In this context we can interpret āṉma-viddai or ātma-vidyā to mean the art and science of self-knowledge, so the import of this pallavi, and hence of this entire kīrtanam, is that knowing oneself is extremely easy.

2020-03-12: Just being self-attentive is extremely simple, because it is a state of perfect oneness, in which one thing is attending to nothing other than itself, and also extremely easy, so if it seems difficult, that is only because our liking to attend to other things is still much stronger than our liking just to be self-attentive

English translation: Oneself exists as so very real even for those who are simple-minded that an āmalaka fruit on the palm ends as unreal. (Ah, extremely easy, …)

Explanatory paraphrase: Oneself exists as so very real [and clear] even for those who are simple-minded that [in comparison] [even] an āmalaka fruit on the palm is found to be unreal [and unclear]. ([Therefore] ah, extremely easy, ātma-vidyā, ah, extremely easy!)

Explanation and discussion: There is an expression in Tamil, ‘உள்ளங்கை நெல்லிக்கனி’ (uḷḷaṅ-kai nelli-k-kaṉi), which literally means ‘palm āmalaka fruit’, and which is used to describe anything that is as clear and certain as an āmalaka fruit on the palm of one’s hand. Referring to this, in this anupallavi Muruganar implies that oneself (ātmā) is so very clear, certain and real that in comparison even an āmalaka fruit on the palm of one’s hand seems unclear, dubious and unreal. That is, there is nothing that is as clear and indubitably real as our awareness of our own existence, ‘I am’.

Since we are always so clearly aware of ourself, knowing ourself as we actually are cannot be difficult. If it seems difficult, that is because we do not yet want it strongly enough, and the reason we do not want it strongly enough is that in order to be aware of ourself as we actually are we must give up forever being aware of anything else, so to the extent we have any desire for or attachment to anything other than ourself we do not wholeheartedly want to be aware of ourself as we actually are. In other words, though we may have a certain degree of love to know what we actually are, we are not yet ready to pay the price that must be paid for it.

The need for us to give up being aware of anything else in order to know ourself as we actually are is explained by Bhagavan in the verses (caraṇaṅgaḷ) of this song.

2020-06-21: Bhagavan used the term ‘நான் நான்’ (nāṉ nāṉ), ‘I am I’, to distinguish our real adjunct-free self-awareness from our false adjunct-mixed self-awareness, namely ego, which he referred to as ‘நான் இது’ (nāṉ idu), ‘I am this’, because ‘நான் இது’ (nāṉ idu), ‘I am this’, denotes a false identity, since it is an identification of ourself with something other than ourself, namely a body consisting of five sheaths, whereas ‘நான் நான்’ (nāṉ nāṉ), ‘I am I’, denotes our real identity, since it is an identification of ourself with ourself alone
2020-04-15: All other thoughts are objects perceived by ego, whereas ego is the subject, the perceiver of them all, so no other thoughts can exist without ego, and hence ego is the one constant thought, the thread on which all other thoughts are strung
2019-09-22: ‘I am I’ is not a circular definition of ‘I’, because it refers to the clear awareness that I am nothing other than I, which is what shines forth when ego, the false awareness ‘I am this’, is destroyed
2019-08-28: ‘நான் நான்’ (nāṉ nāṉ), ‘I am I’, expresses recognition of the fact that I am nothing other than I, because when ego is eradicated, what remains in its place is just pure self-awareness (ātma-jñāna), which is never aware of itself as anything other than itself

2016-06-19: The primary adjunct that is mixed with self-awareness to form ego is a body, so though ego is sentient and a body is an insentient thought, ego is always aware of itself as ‘I am this body’

2015-11-11: Āṉma-Viddai verse 2: our primal thought called ‘I’ is just the illusory experience ‘I am this body’
2014-08-15: Since we never experience the mind without experiencing ourself as a body, Bhagavan often described our primal thought called ‘I’ as the thought ‘I am this body’ (in which ‘this body’ refers to whatever body we currently experience as ourself, whether in waking or in dream)
2014-05-25: Bhagavan describes ego (this thought called ‘I’) as a thought because it is a confused mixture of what ‘I’ actually is and of various adjuncts that it (ego) now experiences as ‘I’, and all such adjuncts (beginning with the body that now seems to be ‘I’) are mere thoughts, so he also described ego as the thought called ‘I am this body’

When one just is, resting [calmly as pure awareness] without the least karma [action] of mind, speech or body, ah, in [one’s] heart the light of oneself alone [will shine forth clearly as ‘I am I’]. [Having thereby drowned and lost oneself (namely ego) forever in this perfectly peaceful and infinitely clear state of pure awareness, it will be clear that this is one’s] eternal experience. Fear does not [or will not] exist. The ocean of [infinite] bliss alone [will remain]. ([Therefore] ah, extremely easy, ātma-vidyā, ah, extremely easy!)

2020-03-31: Āṉma-Viddai verse 4: how can we just be without even the least action of mind, speech or body?
2020-03-12: Just being self-attentive is extremely simple, because that it is a state of perfect oneness, in which one thing is attending to nothing other than itself, and also extremely easy, so if it seems difficult, that is only because our liking to attend to other things is still much stronger than our liking just to be self-attentive
2014-04-11: What one really is is something that is clearly and perfectly self-aware, so ‘remaining still and being simply what one really is’ means just being calmly and clearly self-aware without any action of mind, speech or body
2014-03-20: Bhagavan taught that ātma-vicāra is not only the only means by which we can experience ourself as we really are, but is also the easiest of all kinds of spiritual practice, so it is suitable for anyone who genuinely wants to know what they really are

Psicología MENADEL Clínica y Tradicional

La Psicoterapia (Psicología Clínica Cognitivo-Conductual aplicada con fines terapéuticos) es un proceso de superación que, a través de la observación, análisis, control y transformación del pensamiento y modificación de hábitos de conducta te ayudará a vencer:

Depresión / Melancolía
Neurosis / Estrés
Ansiedad / Angustia
Miedos / Fobias
Adicciones / Dependencias (Drogas, Juego, Sexo…)
Obsesiones
Problemas Familiares y de Pareja e Hijos
Trastornos de Personalidad . . .

Psicología Tradicional (Cuerpo, Alma y Espíritu): “La psicología tradicional y sagrada da por establecido que la vida es un medio hacia un fin más allá de sí misma, no que haya de ser vivida a toda costa. La psicología tradicional no se basa en la observación; es una ciencia de la experiencia subjetiva. Su verdad no es del tipo susceptible de demostración estadística; es una verdad que solo puede ser verificada por el contemplativo experto. En otras palabras, su verdad solo puede ser verificada por aquellos que adoptan el procedimiento prescrito por sus proponedores, y que se llama una Vía”. (Ananda K Coomaraswamy)

La Psicología no trata únicamente patologías. ¿Qué sentido tiene mi vida? El Autoconocimiento, el desarrollo interior es una necesidad de interés creciente en una sociedad de prisas, consumo compulsivo, incertidumbre, soledad y vacío. Conocerte a Ti mismo como clave para encontrar la verdadera felicidad.

Estudio de las estructuras subyacentes de Personalidad
Técnicas de Relajación
Visualización Creativa
Autosugestión
Armonización Energética
Desbloqueo de Experiencias Pasadas
Exploración de la Consciencia

Desvelan el secreto de la producción de dopamina

En una investigación reciente, se ha conseguido identificar el mecanismo de la enzima que produce dopamina, un neurotransmisor clave para la atención, la memoria y el placer.

Un equipo, liderado por investigadores del Consejo Superior de Investigaciones Científicas (CSIC) en España, ha determinado la estructura tridimensional de la enzima clave para la síntesis de dopamina, un neurotransmisor (molécula que ejerce comunicaciones entre neuronas) fundamental en diversas funciones vitales cruciales en los mamíferos, como la coordinación del movimiento, la memoria y la atención, y la sensación de placer, entre otras. Se trata de la enzima tirosina hidroxilasa (TH) y conocer su estructura tridimensional es necesario para determinar tanto su mecanismo como la función que desempeña en la síntesis del neurotransmisor dopamina.

Este conocimiento permitirá comprender el funcionamiento de esta enzima y sentar las bases para el desarrollo de reguladores farmacológicos específicos que puedan ser de utilidad en enfermedades neurológicas como el Mal de Parkinson.

El equipo de investigadores, liderado por José María Valpuesta, del Centro Nacional de Biotecnología (CNB), dependiente del CSIC, en colaboración con el grupo de Aurora Martínez, de la Universidad de Bergen, en Noruega, ha determinado la estructura de la enzima tirosina hidroxilasa mediante la utilización de la criomicroscopía electrónica, una técnica microscópica que analiza muestras a temperaturas criogénicas.

“Este trabajo muestra por primera vez la estructura de la enzima TH, que funciona como un tetrámero, es decir, que consta de cuatro partes. Además, se ha observado el mecanismo de autorregulación de TH mediado por la dopamina”, indica Valpuesta. El investigador explica que “en esta estructura se observa una masa central que se corresponde con un tetrámero donde se encuentran los dominios catalíticos, conectada a dos pequeños volúmenes a ambos lados que contienen los dominios reguladores. La unión entre ambas se realiza a través de una región muy flexible en el extremo inicial de TH, lo que explica la dificultad previa de obtener la estructura completa”.

Esta región tan flexible es fundamental en la estricta regulación de la enzima. Jorge Cuéllar, investigador en el CNB, destaca: “gracias a la estructura general identificada ahora, se puede entender cómo la TH se autoinhibe en presencia de dopamina”. Combinando la criomicroscopía electrónica con métodos bioquímicos, se ha determinado que la actividad de la TH depende de la ubicación de esta región en la estructura global. Cuando en la célula hay suficiente cantidad de dopamina, esta se une al centro activo de la TH, la región flexible se mueve para proteger esta unión y se mantiene la inhibición. Por el contrario, ante una nueva necesidad de dopamina, se activa la fosforilación de la región flexible, que desestabiliza la unión de la enzima y la dopamina, siendo desplazada del centro activo, y la enzima vuelve a funcionar. “El nuevo modelo permite seguir los cambios en la estructura tridimensional de la enzima al unirse con la dopamina y el papel relevante de la región flexible en el funcionamiento o la inhibición de su acción”, recalca Cuéllar.

Tirosina hidroxilasa, clave en enfermedades neurológicas

La producción de neurotransmisores como la dopamina y adrenalina son procesos muy regulados por la importancia de su acción sobre el control motor, la emoción, la recompensa, los biorritmos y el aprendizaje. La tirosina hidroxilasa (TH) es una enzima clave en el metabolismo de estas sustancias y cataliza el paso limitante en su producción. El mal funcionamiento de la enzima puede producir diversas enfermedades neurológicas entre las que se encuentra la enfermedad de Parkinson.

El estudio se titula “Structural mechanism for tyrosine hydroxylase inhibition by dopamine and reactivation by Ser40 phosphorylation”. Y se ha publicado en la revista académica Nature Communications. (Fuente: CNB / CSIC)

Red de neuronas artificiales para estudiar el autismo

Mediante el empleo de un modelo computacional que imita el funcionamiento de la corteza cerebral a partir de estímulos visuales, unos investigadores han identificado una relación entre procesos fisiológicos y perceptuales que tendrían lugar en los trastornos del espectro autista.

“Entender mejor la relación entre la fisiología del cerebro y la percepción o el comportamiento es esencial para diseñar nuevas terapias, aunque todavía queda un largo camino por recorrer para llegar a esa instancia”, indicó Rodrigo Echeveste, doctorado en Ciencias Naturales en Alemania e investigador del CONICET y la Universidad Nacional del Litoral (UNL) en el Instituto de Investigación en Señales, Sistemas e Inteligencia Computacional o “sinc(i)”, en la Ciudad de Santa Fe, Argentina.

Hace unos años, Elizabeth Pellicano, de la Universidad Macquarie, en Australia, y David Burr, de la Universidad de Florencia, en Italia, propusieron que el pesaje o “balance” de la información sensorial del mundo exterior con la información previa, y la forma de representarse probabilidades tanto sobre el mundo exterior como sobre las propias expectativas, se produce de una forma menos eficaz en personas con autismo. Por ejemplo, la percepción sensorial se intensifica y las expectativas se atenúan.

Echeveste y sus colegas se propusieron tratar de entender por qué ese pesaje en personas con trastornos del espectro autista es diferente.

“Para responder a esta pregunta, analizamos observaciones acerca de la fisiología del autismo”, señala el investigador santafesino con un posdoctorado en el Laboratorio de Inteligencia Computacional y Biológica (CBL) de la Universidad de Cambridge, en el Reino Unido.

Modelo computacional

En el estudio se usó como banco de pruebas un modelo computacional que había sido desarrollado por Echeveste junto con investigadores de la Universidad de Cambridge durante su estadía en esa institución.

“Este modelo es una red neuronal que había sido entrenada utilizando técnicas de inteligencia artificial para procesar estímulos visuales, y que imita el comportamiento de nuestra corteza visual primaria. Cuando uno mide cómo se comportan estas neuronas artificiales mientras la red ‘mira’ algo, vemos una dinámica en las respuestas de las neuronas que son muy similares a las de nuestra corteza cerebral”, explicó Echeveste.

El óptimo funcionamiento de nuestro cerebro requiere de un balance muy delicado entre neuronas excitatorias que, cuando se activan, ayudan a encender a otras neuronas, y de otras inhibitorias que, cuando se encienden, tienden a hacer apagar a las demás.

“Concretamente, nos preguntábamos si las diferencias perceptuales (entre personas con y sin autismo) en términos del pesaje de información podrían explicarse a partir de diferencias en los mecanismos de inhibición y, para ello, utilizamos un modelo computacional que simulase el funcionamiento neurológico y fisiológico”, puntualizó Echeveste.

Al debilitar la inhibición en la red neuronal artificial, comenzaban a pesar menos las expectativas previas y más la percepción de los estímulos. “Por lo tanto, al menos en nuestro modelo, estas dos visiones sobre el autismo constituirían dos caras de la misma moneda”, indicó el investigador.

En los últimos años se observa una explosión en la neurociencia del uso de técnicas vanguardistas provenientes del campo de la inteligencia artificial para desarrollar modelos computacionales que permitan entender mejor el funcionamiento del cerebro. “La mayoría de los modelos representan el normal funcionamiento del cerebro. Con este trabajo mostramos que este enfoque también es muy útil para entender el procesamiento sensorial en, por ejemplo, personas con autismo”, indicó Echeveste.

Y agregó: “En un ida y vuelta con la neurociencia experimental, estos modelos, cada vez más detallados y complejos, permiten testear hipótesis y generar predicciones que guíen el trabajo futuro, ayudando a enfocar esfuerzos experimentales, que suelen ser difíciles o costosos de realizar.”

El estudio se titula “Bridging physiological and perceptual views of autism by means of sampling-based Bayesian inference”. Y se ha publicado en la revista académica Network Neuroscience. Entre los autores, también figuran Diego Milone y Enzo Ferrante, también investigadores del CONICET y la UNL en el sinc(i), e Inés Samengo, del CONICET en el Instituto Balseiro y del Departamento de Física Médica en el Centro Atómico Bariloche.
