Kadam (Tibetan Buddhism)
The Kadampa (Tibetan: བཀའ་གདམས་པ་, Wylie: Bka' gdams pa) tradition was a Tibetan Mahayana Buddhist school. Dromtönpa, a Tibetan lay master and the foremost disciple of the great Indian Buddhist Master Atisha (982-1054), founded it and passed three lineages to his disciples. The Kadampa were quite famous and respected for their proper and earnest Dharma practice. The most evident teachings of that tradition were the teachings on Bodhicitta (later these special presentations became known as Lojong (Blo-ljong)) and Lamrim (Stages of the Path) by Atisha.
