Guru Sengé Dradrok
From Rigpa Wiki
From A Great Treasure of Blessings, page 30:
- Guru Rinpoche challenged and defeated five hundred upholders of wrong views in debate at Bodhgaya. He reversed their magic with the aid of a wrathful mantra given him by the lion-faced dakini Marajita.
- He is known as Sengé Dradok, 'The Lion's Roar'.
