In Tibetan religious literature, Jamgön Kongtrül's in ten books stands out as a unique, encyclopedic masterpiece embodying the entire range of Buddhist teachings as it was preserved in Tibet. This volume is the fifth book of that work and is considered by many scholars to be its heart. Jamgön Kongtrül explains the complete code of personal liberation as it applies to both monastic and lay persons, the precepts for those aspiring to the life of a bodhisattva, and the exceptional pledges for practitioners on the tantric path of pure perception.
