Kanheri is on the island of Salsette, about twenty miles north of Bombay. It is in reality a part of the mainland, from which it is separated by a small stream. The ocean surrounds it on the other three sides. In the early years of the Christian era this island was inhabited by monastic members of the Buddhist Order. The great Chaitya Hall is said to have been dedicated by the celebrated Buddhaghosa in the year A.D. 4. There is an inscription to this effect in the entrance. At that time it must have been one of the great Buddhist centres. Buddhaghosa left Kanheri for Ceylon, and from there went to Burma where he introduced Buddhism. He was the great preacher of that age, remarkable for his eloquence and his power as a missionary. His great work. which has come down to modern times, is the Mahamarga — the Great Way.
