Does one require proof of one's own being? Only remain aware of yourself and all else will be known.
Ramana MaharshiSense-perceptions can only be indirect knowledge, and not direct knowledge. Only one's own awareness is direct knowledge.
Ramana MaharshiThe fact is that the mind is only a bundle of thoughts. The mind is fattened by new thoughts rising up. Therefore it is foolish to attempt to kill the mind by means of the mind. The only way of doing it is to find its source and hold on to it. The mind will then fade away of its own accord.
