The Noble Mahāyāna Sūtra “The Seven Buddhas”

The Seven Buddhas opens with the Buddha Śākyamuni residing in an alpine forest on Mount Kailāsa with a saṅgha of monks and bodhisattvas. The Buddha notices that a monk in the forest has been possessed by a spirit, which prompts the bodhisattva Ākāśagarbha to request that the Buddha teach a spell to cure diseases and exorcise demonic spirits. The Buddha then emanates as the set of “seven successive buddhas,” each of whom transmits a dhāraṇī to Ākāśagarbha. Each of the seven buddhas then provides ritual instructions for using the dhāraṇī.
