For the past year I have been preparing a translation of lectures that Ken Rinbochay Tsültrim Gyatso gave at the Rocky Mountain Dharma Centre in 1991. It was my privilege to serve as his oral translator for an extended exploration of Jamgön Kongtrül Lodrö Tayé’s study of the two truths, the selflessness of persons, and the Mind Only and Middle Way Schools. The topics will be familiar, but the interpretations may be less so, for they will introduce a stream of commentary and contemplative practice that were apparently revived and disseminated by Kenbo Tsültrim and a few other scholars. I will set the lectures in context and highlight a few of the more interesting elements of the course he taught in 1991.
