Eight Sadhana Teachings

Eight Sadhana Teachings (sgrub pa bka' brgyad). Eight chief yidam deities of Mahayoga and their corresponding tantras and sadhanas that were transmitted to Guru Rinpoche by the eight Indian vidyadharas: Manjushri Body, Lotus Speech, Vishuddha Mind, Nectar Quality, Kilaya Activity, Liberating Sorcery of Mother Deities, Maledictory Fierce Mantra, and Mundane Worship. Often the name refers to a single practice involving complex mandalas with numerous deities. See also Assemblage of Sugatas and Sadhana Section.
