Ripping down a painting of the ocean, to reveal, the ocean

Of course pure Tao can know itself: but only incarnated as an apparently separate entity, can it see, feel, and touch itself.

Realisation then is where Tao, that which has always been, sees through one of its many minds (who are also completely and utterly Tao) that he is Tao. The separate-ego idea is generally cast off with a deeply felt relief and often inwardly felt and perhaps outwardly audible, laugh.
