This Course is based upon the Compendium on Valid Perception (Pramana Samuchaya) by Master Dignaga (440 AD), the Commentary on Valid Perception (Pramana Varttika) by Master Dharmakirti (630 AD), Light on the Path to Freedom (Tarlam Selje) by Gyaltsab Je (1362-1432), and Jewel of the True Thought (Tsema Gong-gyen) by Geshe Yeshe Wangchuk (1928-present). 

Topics include: the definition of valid perception, the three levels of perception, who has valid perceptions and how, evaluating things beyond our direct perception, how great compassion is developed, the nature of omniscience, the material cause of the mind, proofs of the mind’s source, proofs for the existence of past and future lives, and how desire leads to rebirth – an explanation of crucial links in the chain of dependent origination.
