Translated from Tibetan as “Followers of the Virtuous Path”, Gelug was established in the 14th century by Tsongkhapa, widely regarded as on of Tibet’s greatest Buddhist masters.
Foundations of Gelug: emphasis on monks and nuns to follow the vinaya, the monastic code of ethical conduct that the Buddha had taught.
The Gelug school presents the path to enlightenment as a series of gradual steps in a system called Lamrim or “Stages of the Path”. and emphasizes “the three principle aspects of the path”: renunciation of worldly attachments, the altruistic determination to achieve enlightenment for others, and a correct understanding of the nature of reality.
