When Lobsang Chökyi Gyaltsen died in 1662, the 5th Dalai Lama commenced the tradition of searching for his next incarnation.[23] He also reserved the traditional title of Panchen which had previously been a courtesy title for all exceptionally learned lamas – exclusively for his successors. Khedrub Je, Sönam Choklang and Ensapa Lobsang Döndrup were posthumously decided by the 5th Dalai Lama to have been a previous incarnation of Lobsang Chökyi Gyaltsen, 4th Panchen Lama (1570–1662). Traditionally, there were considered to be four Indian and three Tibetan incarnations before Khedrup, starting with Subhuti, one of the original disciples of Gautama Buddha.
