Nan Yar — Who Am I
If other thoughts arise, one should, without attempting to complete them, inquire “To whom did they arise?” What does it matter however many thoughts arise? At the very moment that each thought rises, if one vigilantly inquires “To whom did this arise?”, it will be known “To me.” If one then inquires “Who am I?”, the mind will turn back to its source and the thought which had arisen will also subside.
— Ramana Maharshi, Nan Yar
