Every poem that works is like a metaphor of the whole mind writing, the solution of all the oppositions and imbalances going on at that time. When the mind finds the balance of all those things and projects it, that's a poem. It's a kind of hologram of the mental condition at that moment, which then immediately changes and moves on to some other sort of balance and rearrangement. What counts is that it be a symbol of that momentary wholeness. That's how I see it.
