Lamdre is a set of teachings and practices foundational to the Sakya tradition of Tibetan Buddhism, which outlines the paths and results of studying philosophical teachings and actualizing Buddhist practices. Although largely focused on Hevajra Tantra, the Lamdre teachings begin with the Mahayana path and Madhyamaka philosophy, which holds that samsara and nirvana are aspects of the same reality. More advanced Lamdre teachings involve the initiations and deity yoga of the Hevajra Tantra. The depiction of Lamdre lineage masters, teachings, and initiations passed unbroken from teacher to disciple are important aspect of Sakya religious art.
