What we call happiness or ecstasy is to me creative thinking. And creative thinking is the infinite movement of thought, emotion and action. That is, when thought, which is emotion, which is action itself, is unimpeded in its movement, is not compelled or influenced or bound by an idea, and does not proceed from the background of tradition or habit, then that movement is creative. So long as thought - and I won't repeat each time emotion and action - so long as thought is circumscribed, held by a fixed idea, or merely adjusts itself to a background or condition and therefore becomes limited, such thought is not creative.
