At the Twin Sala Trees at Salavana, the Buddha Entered Mahaparinirvana.
It was time for the Buddha to leave this world. Under the twin sala trees at Salavana, Buddha converted his last disciple, Subhadra. He briefly talked to his disciples about the essence of the Dharma. He admonished his disciples to learn from abiding in the precepts. At mid-night, on February 15, 364 B.C., the Buddha entered into nirvana, at the age of 80.
