Siddhartha first studied yogic meditation under the teachers Alara Kalama and Udraka Ramaputra, and after mastering their techniques, decided that these did not lead to the highest realization. He then undertook fasting and extreme austerities, but after six years gave these up fearing that they might cause his death before he attained illumination. Taking moderate food, he seated himself under a pipal tree at Bodh Gaya and swore not to stir until he had attained the supreme enlightenment. On the night of the full moon, after overcoming the attacks and temptations of Mara, "the evil one," he reached enlightenment, becoming a Buddha at the age of 35.
