Treasury of Valid Cognition and Reasoning - Chapter 1 (SPOC)

Faculty: Acharya Kelsang Wangdi

This is the first of a series of teachings by Acharya Lama Kelzang Wangdi on Sakya Paṇḍita’s entire Treasury of Valid Cognition and Reasoning. Acharya Lama Kelzang will begin to teach chapter 1, “Investigation of the Object.” This chapter sets
forth the major terminology of the tradition of valid cognition:

  • valid cognition and mistaken cognition,
  • their related objects that are things, non-things, and clearly appearing non-existents, and
  • the modes of engagement of objects as appearing objects, referent objects, and objects of engagement.

The theories of perception of the Vaibhāṣikas and Sautrāntikas are analyzed with a critique from the Mahāyāna schools, using the reasoning of one and many.
