The main practice in the Kagyü teaching system is Mahamudra. The lineage of Mahamudra chiefly comes through Marpa Lotsawa's two root gurus, Naropa and Maitripa. The texts explained here — A Summary of Mahamudra and The View, Concisely Put — were spoken by Naropa.
Naropa's songs are very important for practitioners of Mahamudra, pithy words, rich with meaning. This is why I chose to teach them during my courses. The songs and my explanations are now translated by lotsawa Erik. These teachings are about essential meditation training. I consider them very important for future students to pay attention to and study. Doing so will greatly benefit one's understanding of the key points of Mahamudra. (Thrangu Rinpoche, foreword, 7)
