The Tiratana Vandana
The Tiratana Vandana, or Salutation to the Three Jewels, is the classic Buddhist salute to the Buddha, the Dharma, and the Sangha: the Buddha, his teachings and the Buddhist community. It is chanted every day across the world by practitioners from different Buddhist communities.
