The concept of Sunya in India has a long history and varied manifestations in different dimensions, in mathematics, in philosophy and in mysticism. In mathematical literature it is used in a sense of 'zero' having no substantial numeral value of its own but playing the key role in the system of decimal notation, to express all numbers with nine digits, one to nine and the Sunya as the tenth. The present volume aims at a documented account of various facets of Sunya in mathematics and astronomy and its various ramifications in philosophy.
