About Buddha Nature

In the realm of Buddhist philosophy, Buddha-nature represents the inherent potential within all sentient beings to attain Buddhahood. This concept is frequently translated into English using various related Mahayana Buddhist terms, including "suchness" (tathata). However, two of the most prominent terms associated with this concept are "tathāgatagarbha" and "buddhadhātu."
Tathāgatagarbha can be understood as "the womb" or "embryo" (garbha) of the "thus-gone" (tathāgata), signifying the idea of containing the potential for Buddhahood. On the other hand, buddhadhātu can be literally interpreted as the "Buddha-realm" or the "substrate of Buddhahood."
