The Guhyagarbha Tantra (The Tantra of the Secret Quintessence) is the main tantra of the Mahayoga class and the primary Tantric text studied in the Nyingma tradition as a key to understanding empowerment, samaya, mantras, mandalas and other Vajrayana topics.
Traditionally higher tantras require an empowerment and transmission from a qualified guru or lama before they can be studied and practiced, and were therefore not usually discussed publicly.
