Khedrup Gelek Pelzang (1385-1438) better known as Khedrup Je, the 1st Panchen Lama, was one of the main disciples of Lama Tsongkhapa (founder of the Gelug tradition of Tibetan Buddhism). Before becoming Tsongkhapa's foremost disciple, Khedrup Je had been a learned Sakyapa scholar. He is considered to be a reincarnation of Manjushri, the Buddha of Wisdom. He wrote an important text on Kalachakra initiation which is still used by Tenzin Gyatso, the 14th Dalai Lama, as the basis of his public initiations into the Kalachakra. Altogether, there are nine volumes of his collected works, containing fifty-eight treatises.
