In recognition of his accomplishment of study and meditation, His Holiness the Sakya Trizin requested Lama Kalsang to lead the meditation training sessions during His Holiness' bestowal of the precious Lam Dre teaching cycle in Friday Harbor, Washington in 1995.

At the request of His Holiness the Sakya Trizin and his own students, Venerable Lama Kalsang Gyaltsen has translated numerous major Sakya texts into English.  These include His Holiness' autobiography, the Hevajra Cause and Path Initiations, the Anatomy of the Lam Dre Teaching and numerous other tantric texts, sadhanas and prayers.  His Holiness the Sakya Trizin chose Lama Kalsang to provide simultaneous English interpretation when he bestowed the Collection of All the Sadhanas teaching cycle in Kathmandu in 1994.  Lama Kalsang has also served as interpreter for the teaching tours of His Eminence Luding Khen Rinpoche, His Eminence Dezhung Rinpoche and Venerable Tharig Tulku Rinpoche.
