The Tathāgatagarbha sūtras are a group of Mahayana sutras that present the concept of the "womb" or "embryo" (garbha) of the tathāgata, the buddha. Every sentient being has the possibility to attain Buddhahood because of the tathāgatagarbha. This concept originated in India but was a major influence in the development of East Asian Buddhism, where it was equated with the concept of Buddhadhātu, "buddha-element" or "buddha-nature".
