Patanjali Yoga Sutra #3
Tada Drashtuh Svaroope-vasthanam Then, the seer (Purush) abides in is own nature. This sutra simply states that after prakriti is fully separated, and chitta also dissolves, then the consciousness (purush) still stays, absorbed with its own nature. This looks too obvious in first look to waste a full sutra on. However, there are many schools of thought that believe that once the object of awareness (prakriti) is removed, the purush ceases to exist (in Buddhism), or becomes unconscious (nyaya and vaisheshika schools).To counter these, Patanjali takes an upfront stand. That said, there is question of - so what. what's the point of abiding in own nature? how do prakriti and purush come together in a the first place, vs being forever separate? The answer usually is - don't worry about all this. It won't change anything. Focus on the known challenges in the path of yoga.
