Asalaha Puja

Asalaha Puja Day, according to the traditions of Theravada Buddhism, is the anniversary of the Lord Buddha's first sermon, know as the Turning of the Wheel of the Dharma. He delivered this sermon to the five ascetics who were his attendants during his quest for enlightenment.
In this sermon, the Lord Buddha expounded on the primary founding principle of Buddhist practice and the hallmarks of what he had discovered- the Four Noble Truths, and the principle of practice that leads to it, known as the Middle Way.
As a result, the leader of the five ascetics, Kondanya, was enlightened, and declared himself a disciple of the Buddha.The others were converted to the Buddhist faith and subsequently enlightened and ordained in the same manner.
According to this legend, the first sermon is recognised as the point at which the three components of the Triple Gem, comprising the ultimate entity of worship for Buddhists- the Buddha, the Dharma, and the Sangha- were complete.
