During the Kagyu Monlam, many prayers are recited, but particularly the “King of Aspiration Prayers” or “Samantabhadra Wishing Prayer”. And it comes from a collection of sutras, which contains a great number of aspiration prayers (since sutras are the preserved teachings of Buddha Shakyamuni, these are prayers he himself would have spoken).

This particular aspiration prayer, the “Samantabhadra Wishing Prayer” is said to be the king of all aspiration prayers. Among the sixteen points it has, the first section is the seven-branch prayer.

The collected efforts of all the individuals gathered produce a hundred thousand or more recitations and contribute to the development of positive disposition and wisdom, necessary in order to reach enlightenment for the sake of all sentient beings.
