This pocket-sized handbook contains: the benefits of going for refuge and the refuge vows; the lay Pratimoksha vows; the benefits of bodhichitta, the precepts of aspiring bodhichitta and the root and secondary downfalls of the Bodhisattva vows; the commitments and precepts of training the mind; all the various sets of Tantric vows and commitments. The introduction gives a short but clear explanation of how we can avoid the four main causes of degenerating our Pratimoksha, Bodhisattva, or Tantric vows, which are known as the ‘four doors of receiving downfalls’.
