Lhatsè-drak (lha rtse’i brag) literally means the Rock of Lhatse (Lhatse is a district in upper Tsang). Gayādhara and Drokmi ('brog mi) met and resided at Lhatsè-drak, where the former had a meditation cave. The Chronicle of Tibet explains that the time they spent there came to be known as the ‘month of Dharma’ as a result of their exchanges (Davidson, 166).
Lhatsè-drak appears only once in the Blue Annals. Interestingly, the Blue Annals indicates that Drokmi resided at Lhatsè-drak, where he "revised the translation of the Abhisamayālaṃkārakārikāvṛtti-śuddha-mati-nāma, chiefly propagated the Tantric doctrines and expounded numerous texts," but the site is not mentioned in the context of the initial meeting of Gayādhara and Drokmi (Roerich, 207).
