Buddha Nature

The Buddha's definitive teachings on how we should understand the ground of enlightenment and the nature and qualities of buddhahood.
All sentient beings, without exception, have buddha nature—the inherent purity and perfection of the mind, untouched by changing mental states. Thus there is neither any reason for conceit nor self-contempt. This is obscured by veils that are removable and do not touch the inherent purity and perfection of the nature of the mind. The Mahayana Uttaratantra Shastra, one of the "Five Treatises" said to have been dictated to Asanga by the Bodhisattva Maitreya, presents the Buddha's definitive teachings on how we should understand this ground of enlightenment and clarifies the nature and qualities of buddhahood. This seminal text details with great clarity the view that forms the basis for Vajrayana, and especially Mahamudra, practice.
