The recognition of Panchen Lamas began with Lobsang Chökyi Gyaltsen, tutor of the 5th Dalai Lama, who received the title "Panchen Bogd" from Altan Khan and the Dalai Lama in 1645.[2] Bogd is Mongolian, meaning "holy".[3] Khedrup Gelek Pelzang, Sönam Choklang and Ensapa Lobsang Döndrup were subsequently recognized as the first to third Panchen Lamas posthumously.
