Anuttara Tantra

The Anuttara tantras were also taught by the Buddha. In the land of Ögyan the Buddha, having manifested the mandala of Guhyasamaja, taught King Indrabodhi this tantra. The Yamantaka tantras were taught by the teacher Buddha at the time of the subduing of the demonic forces and they were requested by either the consort of Yamantaka or by the consort of Kalacakra.
