Excerpt About Buddha
Each teaching posits a final or absolute ground of Being that forms the irreducible simplicity of true nature. We refer to this ground as the absolute dimension of Being. The understanding of this ultimate true nature of the self and everything differs in subtle ways from one teaching or philosophy to another. In Christianity, it is the father who is the inscrutable darkness; in Kabala, it is the ain (nothing) or ain sof (infinite); in Sufism, it is the divine Essence; in Buddhism, it is emptiness (sunyata) or Buddha nature (tathagatagarbha); in Taoism, it is the Tao or the nothing; in Vedanta, it is the Brahman or absolute self; in Kashmir Shaivism, it is Shiva; and so on. The spiritual quest becomes that of the soul integrating this ultimate nature as its inner nature, source, and sometimes its identity.
