"Without nothingness, there is no naturalness–no true being. True being comes out of nothingness, moment after moment. Nothingness is always there, and from it everything appears. But usually, forgetting all about nothingness, you behave as if you have something. What you do is based on some possessive idea or some concrete idea, and that is not natural."
from Zen Mind, Beginner's Mind by Shunryu Suzuki
