O Asalha Puja It celebrates the first structured speech the Buddha delivered after his enlightenment and is celebrated on the full moon of July (the full moon of the eighth lunar month of the Indian calendar). This discourse is called ‘Dhammacakkappavattana sutta’ and it was with it that ‘the wheel of the Dhamma was set in motion’ (here Dhamma means teaching). It contains the essence of the Buddha’s subsequent teaching, addressing the ‘Four Noble Truths’.

It was at the end of this discourse, after Venerable Kondanno had fully understood it, that the Buddhist monastic order began.

This day is also known as Dhamma Day and is an opportunity to deepen the Buddha's teachings. It also marks the beginning of vassal.

Thus, after the usual 7:30 p.m. meditation, there will be a Dhamma lecture by Ajahn Vajiro. After the lecture, everyone is also invited to join the Sangha and practice meditation until midnight.
