Friends, it is from Purusha that virtual prakriti got experiential existence. Before the experiential brain was formed, prakriti was running the universe despite being virtual like a shadow. It means it had no existence of its own, like the shadow of a tree. When the first experiential brain was formed, its nerve impulses generated waves inside Purusha. The purusha felt it, due to which darkness engulfed Purusha’s own infinite light-form soul. It means Purusha became Prakriti. However, the nerve impulses in the form of thoughts that kept emerging in the brain, were felt luminous and conscious like Purusha. It means the Prakriti-Purusha pair was born. It is like a tree broke down in a storm and fell on its own shadow and became non-existent like the shadow. Earlier, due to the shaking of the tree due to the storm, its sketches were being made and erased on its shadow. But due to the emergence of new buds from the stump of that tree, a new tree was formed again. Now the silhouettes of that new tree started forming on that old fallen tree. Meaning, the shadow of the tree had also come into existence and the shadow-images of the new tree on it also started feeling like a real tree. Same thing happened with Purusha. Of course, Purusha in the form of light became Prakriti in the form of darkness by feeling his waves. But there was also an original Purusha who never feels anything except himself, that is, his pure soul, not even his waves being created inside him. Therefore, he can never become Prakriti by losing his soul. He can be called Scriptures based Purushottam. Purusha is just like the sky. You can make as many skies as you want from one sky.
The proof of the above fact is found in Kundalini awakening. During Kundalini awakening, the soul feels in the form of infinite light, and the entire creation is felt in it in the form of waves. But as soon as the man starts getting attached to those waves of creation, the infinite light of the soul disappears. Means the shadow of the purusha comes into existence. Actually it existed even before physically, this gave it experiential means self-form existence. Meaning now the shadow has started to feel that it exists. Earlier it was like clay and stone. Similarly they also do not feel that they exist in the spiritual or self form, but they exist in the physical form. Man again, like before, starts feeling his soul as dark prakriti and the mental thoughts flowing in it as luminous purusha-waves. Purusha-waves are created only when an ever stable purusha, that is, Purushottam, is sitting in the background. Otherwise, where will the waves come from? In this way sometimes, I feel that Kundalini awakening is the basic principle of Sankhya philosophy.
