Let’s take the discussion further from here. Note that the title “Two against one” comes from the book “The dice game of Shiva” and pertains to the dualism of samkhya vs. the monism of advaita vedanta. it also fits our earlier discussions, where two adepts of advaita Vedanta (me and Surya) discussed with one adept of classical samkhya (i.e. not Surya’s monist version thereof), namely Asuri. I hope more contributions from others will come and who knows, perhaps the balance will shift from two to one to something different, if the weight of many dice thrown decides so…
Patanjali has provided a nice tweak to Samkhya and swiftly erased any conflict between duality and non-duality. According to him, Yoga meaning Union is between two - purusha and prakriti, so that they unite, or prakriti merges in purusha.
Prakriti being the changing and the finite has to arise from and dissolve in that which is not changing and infinite. Patanjali also provides a very subtle distinction - prakriti is that aspect of purusha, which is born in the process of awareness; hence, the distinction. Ordinary perception cannot perceive purusha and ends up taking its perceived version as the reality. Yoga is that process which enables just “being” in place of “becoming” to realize that the ultimate reality is purusha and not prakriti.
Thus, Patanjali’s yoga requires existence of dual aspects as sell as their union into One. It is human to expect duality and non-duality as two mutually exclusive approaches. It is transcendental to know that both are simultaneously true.
