10 levels of the tree of the universe:

Black - spiritual slavery
Red - magic
Orange - shamanism
Yellow - astral projection
Green - healing
Blue - knowing
Indigo - telepathy
Violet - alchemy
White - spiritual freedom

The 10th level is invisible (it has no name and no reference, but "I called it Tao"), the 9th level is barely visible.

BTW don't fall into a trap of thinking that the black 1st level is 'worst' than 10th or any other. I want to have a full spectrum of the universe.
