This episode focuses on the idea of liberation in Patanjali's Yoga Sutra (Patanjala-yoga-shastra). We touch a little on how Patanjali's system inherits key aspects from the Upanishads, and then focus on the first four sutras of chapter one, which constitute what is known as the classical definition of yoga. From these foundational sutras, it is possible to get a solid sense of how Patanjali frames a simple definition of Yoga, the nature of the problem of ignorance that Yoga intends to address, and the nature of the liberated state. Crucially, the discussion lends nuance - in a surprising way - to the common notion that Yoga - as "union" - is the desired end of our practices.
