Once Buddha was sitting in an assembly, consisting of Bodhisattvas and others. He was requested by the assembly to reveal the *Guhyasamāja*. Thereupon, he sat in different *Samādhis* (meditations) and uttered different kinds of Mantras and transformed himself in different forms of Tathāgatas, called Dhyāni Buddhas, their Śaktis or female counterparts and the four guardians of gates.
