Lamdre - Dawn of Enlightenment is written by Lama Choedak Yuthok. Lama Choedak Yuthok gives a series of lectures on the priceless Lamdre teachings of Tibetan Buddhism's Sakya school. Lamdre is a complete enlightenment route. The Hevajra Tantra underpins the exceptional features of Lamdre teachings. They were first received by the Indian Mahasiddha Virupa in the 7th century, who established the lineage and passed on the teachings to a line of pupils in India. Virupa also wrote Vajragatha, or pith instructions.
