When a man is free from all sense pleasures and depends on nothingness he is free in the supreme freedom from perception. He will stay there and not return again. It is like a flame struck by a sudden gust of wind. In a flash it has gone out and nothing more can be known about it. It is the same with a wise man freed from mental existence: in a flash he has gone out and nothing more can be known about him. When a person has gone out, then there is nothing by which you can measure him. That by which he can be talked about is no longer there for him; you cannot say that he does not exist. When all ways of being, all phenomena are removed, then all ways of description have also been removed.

(Buddha Sakyamuni)
