The Sutra of the Great Drum (Skt. Mahābherīhārakasūtra; Tib. འཕགས་པ་རྔ་བོ་ཆེ་ཆེན་པོའི་ལེའུ་ཞེས་བྱ་བ་ཐེག་པ་ཆེན་པོའི་མདོ་, pakpa ngawo ché chenpö le'u shyé jawa tekpa chenpö do, Wyl. phags pa rnga bo che chen po'i le'u zhes bya ba theg pa chen po'i mdo) — one of ten sutras that teach the sugatagarbha.
In this text buddha nature is possessed by all sentient beings and is described as luminous and pure. It is also attributed characteristics, such as being permanent, eternal, everlasting, peaceful, and a self, that echo the four perfect qualities (guṇapāramitās) often ascribed to the dharmakaya when it is treated as a synonym for buddha nature. It also connects tathagatagarbha to the notion of a single vehicle and asserts the definitive nature of the buddha nature teachings in general and within this sutra in particular.<ref>Tsadra Foundation page (see link below)</ref>
