Wyl. padma las 'brel rtsal) (1248 or 1231/2-1307?)— the immediate reincarnation of Princess Pema Sel to whom Guru Rinpoche had entrusted the transmission of the Khandro Nyingtik in the eighth century. Pema Ledreltsal withdrew the terma of Khandro Nyingtik from its place of concealment at the Daklha Tramo Drak rock in the province of Dakpo, but only partially decoded it during his life. He then transmitted these teachings to his main disciple Gyalsé Lekden. Pema Lédrel Tsal was reincarnated as the Omniscient Longchenpa, who received the whole cycle of Khandro Nyingtik from Gyalsé Lekden, and by so doing, ensured that the authentic lineage was kept alive.
- The Nyingma School of Tibetan Buddhism, Its Fundamentals and History, vol. 2, as well as the TBRC give his year of birth as 1248. Nyoshul Khenpo, in A Marvelous Garland of Rare Gems: Biographies of Masters of Awareness in the Dzogchen Lineage, gives the Female Iron Hare year (1231/2) as his year of birth. His estimated date of death is based on the year of birth of his next incarnation—Longchenpa, born in 1308.
