. The Nature of Buddhist Esotericism
Esotericism of the Buddhist Tantras begins with what are called the "three mysteries of the Buddha," but these could also be translated the "three secrets of the Buddha". As Padmavajra explains them in his Tantrdrthdvatdra Commentary (Toh. 2502, Derge ed. , 1 47a-2, ff.), the secret Body, Speech, and Mind of the Tathagatas, are these :
Secret of Body : Whatever form is necessary to tame the living beings. Secret of Speech : Speech exactly appropriate to the lineage of the creature, as in the language of the yakLa-s, etc. Secret of Mind : Knowing aU things as they rea1ly are.
