Coming to Zero

The Buddha gave one very short discourse that expresses the insight of selflessness very succinctly:

"Whenever you see a form, let there be just seeing; whenever you hear a sound, let there be just hearing; when you smell an odor, let there be just smelling; when you taste a flavor, let there be just tasting; when you experience a physical senseation, let there be just sensing; and when a thought arises, let it be just a natural phenomenon arising in the mind.  When it is like this, there will be no self, there will be no moving about here and there, and no stopping anywhere.  That is the end of dukkha, the end of suffering."
