This book explores the bizarre but fascinating world of infinity in different disciplines of knowledge; mathematics, science, philosophy and religion. It projects the views of eastern as well as western scholars. This world is not only mysterious but also mysterious but also treacherous and conceals many conudrums such as multitude of infinities, the mystic's experience of the infinite, conception of God as absolute infinity. The author also also discusses many paradoxes relating to space and time. It is interesting to discover that some eastern philosophies try to reconcile two opposite concepts of sunya (zero) and ananta (the infinite). The author also ventures to address a difficult question: Does infinity really exist as a physical reality?
