Carl Jung and many before him would call the integrative experience my soul, but not wanting to claim too much or depend on a word worn smooth with use, I prefer to call it my poem-self. The fusion of my three ordinary states of being heightens each one of them, and produces an excitement frequently so intense that I can’t bear it for too long at a stretch, but must get up and run outside for rests from it, then come back for some more. The poem I write during this experience will contain the experience, the more strongly the better the poem is, and will continue to contain it after the trance has left me. What I create, really, is a new body made of words and the potent arrangement of words, in which my soul as it was at a particular moment will go on existing.A Defence of Poetry by Les Murray (1998).
In Murray's account, the three states of being are the waking consciousness mind, the occult mind of dreams, and the body.
