Atisha (982 - 1052) arrived in 1039 at Tibet invited by King Yeshe Od, to help the restoration of Buddhism. His arrival marks the beginning of a new period in the history of Buddhism in Tibet. With the help of his disciple Dromtompa he laid the foundations of the Kadampa tradition. For more than ten years he worked spreading his religion, laying the roots of the expansion that followed him. He confirmed initiations, built monasteries in addition to writing, translating and editing more than 200 books, which helped the development of Buddhism in Tibet. Highlights the poem A lamp in the path of enlightenment that gave rise to the tradition of Lamrim.

One of his most important legacies was the development of mind training practices (lobjong), and the centrality of concept and practice of bodhicitta in Tibetan Buddhism, incorporated into the four schools: Gelug, Nyingma, Kagyu and Sakya. For these reasons Atisha is a central figure in the history of Buddhism.

Je Tsongkhapa (1357 - 1419) was an important teacher of Tibetan Buddhism who was born in Tibet and created the so-called Gelug tradition. Tsongkhapa studied and learned from all schools but his main inspiration was that of the Kadam Tradition founded by the teacher Atisha. He was a Guru of the lineage of Mahamudra Tantra and Buddhists believe in him as the emanation of Buddha Manjushri, the Buddha of wisdom.
