“In Indian mathematics, the zero sign is shunya, but it has quite a different meaning from ‘zero’ in the West. When we think of zero, we think ‘nothing,’ but in India the circle of shunya, or zero, means ‘fullness,’ ‘completeness,’ or ‘wholeness.’ In the same way, ‘emptiness’ does not mean nothingness,’ but rather ‘fullness’ in the sense of full potential—anything can happen in emptiness and because of emptiness.”
