Thinking is only a small aspect of consciousness. Thought cannot exist without consciousness, but consciousness does not need thought.
Enlightenment means rising above thought, not falling back to a level below thought, the level of an animal or a plant. In the enlightened state, you still use your thinking mind when needed, but in a much more focused and effective way than before. You use it mostly for practical purposes, but you are free of the involuntary internal dialogue, and there is inner stillness. When you do use your mind, and particularly when a creative solution is needed, you oscillate every few minutes or so between thought and stillness, between mind and no-mind. No-mind is consciousness without thought. Only in that way is it possible to think creatively, because only in that way does thought have any real power. Thought alone, when it is no longer connected with the much vaster realm of consciousness, quickly becomes barren, insane, destructive.
The mind is essentially a survival machine. Attack and defense against other minds, gathering, storing, and analyzing information - this is what it is good at, but it is not at all creative. All true artists, whether they know it or not, create from a place of no-mind, from inner stillness. The mind then gives form to the creative impulse or insight.
