Kenneth F. Thornton II's video: The Caves of Milarepa Part -2 3 Documentary

Marpa told Milarepa to practice solitary meditation in caves and mountain retreats, which, according to the biography, after many years of practice resulted in "a deep experiential realization about the true nature of reality." Thereafter he lived as a fully realized yogi. Milarepa lived during the so-called second dissemination of Buddhism in Tibet (10th–12th century), when Buddhism was re-introduced. Three pivotal figures in this Tibetan Renaissance were Rinchen Zangpo (958–1055), who translated sutras, tantras and commentaries; Atiśa (982–1054), whose student Dromtön founded the Kadam school of Tibetan Buddhism; and Marpa Lotsawa, the teacher of Milarepa, and himself regarded as student of Naropa. Marpa introduced tantric texts and oral instructions from the Bengali siddha tradition into Tibet, and Marpa's purported connection with Naropa established the lineage of the Kagyu school, thereby reaching back to the Buddha himself.[ "May I be far removed from arguing creeds and dogmas. I have forgotten all difference between myself and others. I have forgotten all those who rule by power. Accustomed long to meditating, I have forgotten all that is said in written and in printed words. I have forgotten to think of hope, I have forgotten the dread of birth. I have forgotten all creeds and dogmas. I have forgotten all definitions, all man-made meditations, and all artificial usages." ~ Hundred Thousand Songs of Milarepa
