guru yoga (Skt)
In order to amass the two collections of merit and purify negativities and obscurations, one views the guru as inseparable from a deity and/or from the Buddha. There are various guru yoga practices, some are done in accordance with tantra, for example, Guru Puja, and some in accordance with the sutra tradition, for example, the Hundred Deities of the Land of Joy (Ganden Lha Gyäma).
