Q. Isn’t it the ego that wants to turn within or end the ego?
Tom: yes, it is only the ego, also known as thought or mind, that requires a teaching or needs to turn within.
Because the ego-I is an unreal illusion and doesn’t really exist, when it turns within towards the Subject or I AM, the ego and all multiplicity/duality disappear and the (true) Self is revealed as Self by the Self.
Through (the ego) turning within, the Reality that is Eternal Timeless Thoughtless Bliss-Love is revealed. This Reality is what you are, what you have always been, and is beyond words, but the above words (…thoughtless bliss…) are just used as indicators.
Without turning within, it is merely the ego proclaiming ‘there is no ego’ or ‘all is already perfect’ or something similar, and the teaching remains on the superficial levels of concepts and words only, and the illusion of suffering and duality continue.
As long as ego-mind-thoughts persist, there is need for effort or spiritual practice (sadhana), for ego-mind-thought is duality, ego-mind-thought is suffering.
As long as separation or multiplicity is perceived in any way shape or form, there is need for effort or sadhana.
As long as identification with body-mind continues (and therefore desire, fear and suffering continue), there is need for effort or sadhana.
However the Self itself is beyond any such efforts!
Oh, the paradox! However, turn within towards your Self, towards I AM, towards the Subject, and all these paradoxes will be resolved and dissolved in the Reality-That-Is.
