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 in deeming oneself better than others nor any reason for self-contempt, thinking of oneself as inferior and unable to reach enlightenment. This seeing is obscured by veils that are removable and do not touch the inherent purity and perfection of the nature of the mind as such. The Mahayana Uttaratantra Shastra, one of the Five Treatises said to have been dictated to Asanga by the Bodhisattva Maitreya, is presented here to clarify the pure qualities of buddhahood.
