The Tathagatagarbha Sutra is an influential and doctrinally striking Mahayana Buddhist scripture which treats of the existence of the "Tathagatagarbha" (Buddha-Matrix, Buddha-Embryo) within all sentient creatures. The Buddha reveals how inside each person's being there exists a great Buddhic "treasure that is eternal and unchanging". This is no less than the indwelling Buddha himself. Only a Buddha can see this "inner Buddha" - ordinary, "unawakened" persons lack the necessary vision, as the "Tathagatagarbha" is covered and obscured by innumerable mental/moral contaminants (notably greed, anger and ignorance). The Buddha comments:
" ... when I regard all beings with my Buddha eye, I see that hidden within the klesas [ = mental afflictions] of greed, desire, anger, and stupidity there is seated augustly and unmovingly the tathagata's [ = the Buddha's] wisdom, the tathagata's vision, and the tathagata's body. Good sons, all beings, though they find themselves with all sorts of klesas, have a tathagatagarbha that is eternally unsullied, and that is replete with virtues no different from my own." (Buddhism in Practice, p. 96).
The Buddha of this scripture urges faith in its teachings on the part of its auditors and insists that the upholding of this sutra will turn the faithful follower into a "Dharma King", a Buddha like himself. The ultimacy of the tathagatagarbha doctrine (from the Mahayana standpoint) as articulated by the sutra is indicated by the exalted nature of the audience to whom it is delivered - an audience which includes Manjusri (embodiment of supreme Wisdom), Avalokitesvara (the manifestation of highest Compassion), and the future Buddha, Maitreya (personification of limitless
Loving-kindness).
The Tathagatagarbha Sutra constitutes one of a number of Buddha-nature sutras (including the Mahaparinirvana Sutra, the Srimala Sutra, and the Anunatva-Apurnatva-Nirdesa scripture) which apodeictically declare the reality of an Awakened Essence within each being. Buddhahood is thus taught to be present inside the mind of every sentient being from the beginningless beginning - but its disclosure to direct perception depends on successful inner spiritual cleansing.
