According to various early texts like the "Mahāsaccaka-sutta," and the "Samaññaphala Sutta," on awakening, the Buddha gained insight into the workings of karma and his former lives, as well as achieving the ending of the mental defilements ("asavas"), the ending of suffering, and the end of rebirth in saṃsāra. This event also brought certainty about the Middle Way as the right path of spiritual practice to end suffering. As a fully enlightened Buddha, he attracted followers and founded a "Sangha" (monastic order). He spent the rest of his life teaching the Dharma he had discovered, and then died, achieving "final nirvana," at the age of 80 in Kushinagar, India.
