He who sees Me, the supreme Reality, everywhere, and everything in the supreme Reality, never loses the Supreme nor is he lost to the Supreme.
Krishna re-states what he conveyed in the previous verse, giving his own personal imprint to the vision. In all such statements, Krishna’s status is that of the Knower Guru, who is the last word for the disciple in his spiritual quest and fulfilment. Being so, Krishna identifying himself with the supreme Reality, is of paramount importance. As the supreme Reality will itself not speak, the gap is filled significantly by personal statements like this.
The ‘I’ Krishna refers to denotes the Self, pure Consciousness. And that is the Self in everyone. What we call God or supreme Reality is no other than this impersonal, imperishable spiritual presence, sentience.
So, by pronouncing in this manner, Krishna confirms that the Self is itself God and Brahman. Each is synonymous with the rest, a fact people in general do not know, but the seeker should not miss, and should be guided by. To see the Self in all is like seeing God in all. By this Krishna gives a devotional touch to his words.
