After having practiced all forms of the severest austerities in Uruvela Forest for six long years, on the full-moon night of Wesak in 528 BCE, the Buddha, endowed with Perfections (Paramis) fulfilled in his last existence, attained the Perfect Enlightenment (Sama Sambodhi) under the Bodhi tree, developing the three extraordinary knowledges–the supernormal ability to remember his past lives, the supernormal vision to see the death and rebirth of beings, and the supernormal knowledge with regard to the destruction of passions and the comprehension of things as they truly are.
