He who has gained yogic integration with equal vision everywhere, perceives the Self as abiding in all beings, and all beings as dwelling in the Self.
Apart from being a personal, inner, subjective experience, Krishna says that Self-knowledge becomes a full vision, adorning the mind and intelligence. Though senses help in begetting object experiences, actual experience is of, from and in the mind.
These, in turn, are evaluated by intelligence, resulting in knowledge, memory and the like. What is the change or enrichment this great spiritual experience brings in the intelligence level? Krishna says the yogi understands that all experiences are mind-born, mind-subsisting.
It is the mind that always takes imprints of objects, though helped by senses. Every time we see, hear and otherwise perceive these imprints alone. Our experience, knowledge, etc. are thus subject-based, solely inner.
So, nothing exists as an object. All objects are subject- imprints alone, hence are one’s own Self. And the Self exists in all beings, bestowing the real equal vision.
