Hi there, I think that it is related to deep meditation - i.e. on a physical and spiritual level. I think that it is when the ego begins to disappear. Many artists feel like this. When they are 'lost' or 'absorbed' in what they are doing only to find that it is not a mindless loss but rather quite an awareness. In a philosophical way, I suggest you read "The Zen Teachings of Bodhidharma" which you can download from . . . http://hjem.get2net.dk/civet-cat/zen-writings/teachings-of-bodhidharma.htm Peace and love Anu
