Brilliant Illumination Of Lamp Of Five Stages is written by Tsong Khapa Losang Drakpa. The Extremely Brilliant Lamp is Tsong Khapa's most important commentary on the Esoteric Community's completion stage practices, the Tantra he believed vital for the practice of the Unexcelled Yoga Tantras' "Father Tantra" class.
It draws heavily on Nagarjuna's Five Stages and Aryadeva's Lamp that Integrates the Practices, as well as a vast range of perfection stage works included in the Tibetan Kangyur and Tengyur collections. It is a significant piece of research for both academics and practitioners.
