Drak Yerpa (Wyl. brag yer pa) is a holy place of Guru Padmasambhava. In this place of great scenic beauty there are over 80 caves where many great beings from all lineages meditated. On the top are the caves of Guru Padmasambhava and of Yeshe Tsogyal (Tib. Sang Puk; Wyl. gsang phug). Below is Drubtop Puk (Wyl. grub thob phug), the great cave where the 80 siddhas of Yerpa (Guru Padmasambhava's disciples) meditated together. There is also Lord Atisha's cave (Tib. Tendrel Puk; Wyl. rten 'brel phug).
