Drepung Gomang Monastic University is one of the most reputed centers (the three great seats: Drepung, Gaden and Sera) for learning, contemplating and practicing Tibetan Buddhist thoughts and science notably known as the second Nalanda University in Tibet. As prophesied in Langsheg Sutra by Lord Buddha: When once Nagaraja Madhopa pledged Lord Buddha with a white conch, Lord Buddha handed it over to Maugalayana, one of his two closest attendants who possessed transcendental miracle-power, with blessed and instructive decree to take it to Gogpa Ri (Garlic Hill) at Gaden in Tibet and hide it there in the hill. It adds that in the future the Bhiksu of Lotus-purity in nature would unearth it and it would thereafter be used as Tsogdhung, to be blown as the signaling medium for gathering to spiritual congregation......
