The excerpt below is taken from the text Aham Sphurana (see here to find out more about this text and download a copy for free), 8th September, 1936:

Questioner: How is it that without a mind, Bhagavan is able to conduct rational converations with us and engage in many other tasks and functions besides?

Bhagavan Sri Ramana Maharshi: Causality is unknown to the Jnani; the Emancipated-one’s actions therefore are always bereft of motive, purpose or volition. Bhagawan does not act at all. Action is alien to the Self; He is Life Itself, but yet absolutely motionless. He is simply AWARE. Other than fullness of Being-consciousness, which he abides as, he does not know anything.

The body may act in the world or remain idle; He cannot know. The faculties of sensory perception may remain inactive or function so as to take cognition of objects in the world; He cannot know. Being the Self, the Jnani is totally ignorant of anything and everything but the Self. He is referred to as the Witness-consciousness transcending space, time and causality; but that is exclusively from the point of view of objects with name, form and shape that take their origin in Him, subsist in Him, and dissolve back into Him, being merely appearances in Him, of Him and by reason of Him; He Himself has nothing to witness or see. The body might be working day and night like a steam-engine, but no karma can touch Him. His sensory-organs might be experiencing the greatest of pleasures, but He enjoys nothing. No matter what manner of work the body might be engaged in doing, He never does anything.

K.: Maharshi, please clarify this one thing for me: are you, or are you not, now talking to us?

B.: No. “I” am not talking to you.

K.: [reflectively] That’s right. Maharshi is not doing any talking. Maharshi simply IS.

Chadwick: I am sometimes given to wondering how a Jnani’s awareness of the Self could formerly have been obscured or obstructed by prior ignorance. Was there ever ignorance for a Jnani?

B.: No.

C.: Are Jnanis born Jnanis then?

B.: One’s idea that one took birth is merely mental information. When mind is annihilated, there is nothing to falsely inform the Jnani that he was born. Therefore, the Emancipated-one abides in perpetuity as the Unborn, to which time, space and any other transformation or possibility of measurement is wholly alien. We point to the body of the Emancipated-one and give it the name ‘Jnani’, thinking that such person must have awareness of the Self. But what is the fact? Is there anybody who can both stand apart from the Self and yet know the Self? The only way to know the Self is to BE It. So, the Jnani is verily Jnana and nothing but Jnana. There are no Jnanis. Jnana IS, Jnana alone IS, and Jnana alone could ever BE.

K.: [in an over-awed cadence of voice] Maharshi, you inspire me. I also want to become great like you; I want to attain your same greatness; I want to become as great as you. I consider it my life’s mission to emulate you. You are my idol, my super-hero. Please tell me what I should do to attain the same greatness that you have attained: you the incomparably great Bhagawan Ramana.

Chadwick: Impossible and inconceivable. How could anybody become our Bhagawan? He is God Absolute.

B.: [smiling] What is there in it? Only remain still [- i.e., summa iru].

K.: Maharshi, I would like to know how I shall get rid of all my sin.

B.: Original sin and original ignorance are all one and the same thing. To get rid of the one is to get rid of the other, and the other the one. Pursuing the investigation ‘Who am I?’ all the way to its successful culmination in Realisation, you will surely get rid of all your sin.

K.: Is the investigation ‘Who am I?’ easy or difficult?

B.: It is the easiest thing there can be. If attending to other things is readily possible for you, imagine how much more easier should be attending to yourself, and attending to yourself exclusively!

K.: Some say that it is exceedingly difficult.

B.: Pay no attention to their words. Do you trust Bhagawan or not?

K.: Implicitly and absolutely.

B.: Then never mind what others are saying. Regard only what is said here.

Bhagawan [tapping right cheek with palm multiple times rapidly and then pointing to own face] says vichara is easy. Will you practice it or not?

K.: [eyes swimming in barely suppressed tears, voice choked and face convulsed with emotion] Yes, Bhagawan.

B.: [smiling] Good.
