Thereafter the Buddha spent the vassa ⁿ²⁸ at the Deer Park at Isipatana, sacred this day to over 600 million of the human race. During these three months of "rains" fifty others headed by Yasa, a young man of wealth, joined the Order. Now the Buddha had sixty disciples, all arahats who had realized the Dhamma and were fully competent to teach others. When the rainy season ended, the Master addressed his immediate disciples in these words:

"Released am I, monks, from all ties whether human or divine. You also are delivered from all fetters whether human or divine. Go now and wander for the welfare and happiness of many, out of compassion for the world, for the gain, welfare, and happiness of gods and men. Let not two of you proceed in the same direction. Proclaim the Dhamma that is excellent in the beginning, excellent in the middle, and excellent in the end, possessed of meaning and the letter and utterly perfect. Proclaim the life of purity, the holy life consummate and pure. There are beings with little dust in their eyes who will be lost through not hearing the Dhamma, there are beings who will understand the Dhamma. I also shall go to Uruvelâ, to Senânigama, to teach the Dhamma."n²⁹

Thus did the Buddha commence his sublime mission, which lasted to the end of his life. With his disciples he walked the highways and byways of India enfolding all within the aura of his boundless compassion and wisdom. Though the Order of Monks began its career with sixty bhikkhus, it expanded soon into thousands, and, as a result of the increasing number of monks, many monasteries came into being. In later times monastic Indian universities like Nâlandâ, Vikramasilâ, Jagaddalâ, Vikramapuri, and Odantapuri, became cultural centres which gradually influenced the whole of Asia and through it the mental life of humankind.

After a successful ministry of forty-five years the Buddha passed away at the age of eighty at the twin Sâla Trees of the Mallas at Kusinârâ (in modern Uttara Pradesh about 120 miles northeast of Benâres).ⁿ³⁰
