The "I" thought

That which arises as "I' in this body is the mind .If one inquires as to where in the body the thought "I" rises first , one would discover that it rises in the heart .That is the place of the mind's origin .Even if one thinks constantly "I-I", one will be led to that place .Of all the thoughts that arise in the mind , the "I" thought is the first .It is only after the rise of this , that the other thoughts arise .

Sri Ramana Maharishi
