The Geluk tradition is one of the major schools within Tibetan Buddhism, established by Tsongkhapa (1357-1419) and now guided by His Holiness the Dalai Lama. Renowned for robust scriptural study and the Stages of the Path (Lam Rim) literature, modern masters include favorite Wisdom authors Lama Zopa Rinpoche and Lama Thubten Yeshe.
