What are tantras?/What is Tantra?
The tantras are the root scriptures of Vajrayana. The tantras are texts ascribed to the Buddha in various manifestations. They usually describe the mandala, mantra, and practice associated with a particular deity/enlightened being. The sexual symbolism of tantric sacred art has led to some misunderstandings. Tantric texts are not ‘pillow books’, and their practice depends on discipline, not indulgence.
