however, a specifically "gelug" mahamudra system was only recorded at the time of lobsang chökyi gyaltsen, 4th panchen lama (sometimes named the "1st panchen lama", 1570-1662), who wrote a root mahamudra text on the ""highway of the conquerors: root verses for the precious geden [gelug] kagyu [oral] transmission of mahāmudrā"" ("dge-ldan bka'-brgyud rin-po-che'i phyag-chen rtsa-ba rgyal-ba'i gzhung-lam") and its auto commentary (the "yang gsal sgron me, "lamp re-illuminating mahamudra""), which is still widely taught and commented upon. before this work, gelug writings on mahamudra tended to follow orthodox kagyu teachings. this text and its auto commentary have become a central work on mahamudra in the gelug school. the current 14th dalai lama and lama yeshe are some of the modern gelug figures which have written commentaries on this key gelug mahamudra text.
