It is the fifth century. Ajita, a curious young boy, is endlessly fascinated by ants. How do they know where to seek food? How do they move in such orderly fashion? Do they communicate? These questions ignite his lifelong pursuit of knowledge. In the course of Ajita’s evolution into a philosopher of the Cārvāka school, his life crosses paths with many interesting characters: from Emperor Ajatashatru to Makkhali Goshala, Mahavira and the Buddha.
