The present work is the cornerstone of Treasury of the Buddhist Sciences series.
Compromised of the collected work of Tsongkhapa Losang Drakpa (1357-1419) and His Spiritual Sons - Gyaltsap Darma Rinchen (1364-1432) and Khendrup Gelek Pelsang (1385-1438) - this Collection is a voluminous set of independent Tibetan treatises and super commentaries.
It draws heavily on Nagarjuna's Five Stages (Pancakrama) and Aryadeva's Lamp the integrates the Practices (Caryamelapakapradipa), as well as a vast range of perfection stage works included in the Tibetan Kangyur and Tengyur collections.
The Brilliant Illumination of the Lamp of the Five Stages is Tsongkhapa's most important commentary on the perfection stage practices of the Esoteric Community (Guhyasamaja) - the Tantra he considered fundamental for the practice of the "Father Tantra" class of Unexcelled Yoga Tantras.
