यो मां पश्यति सर्वत्र सर्वं च मयि पश्यति | तस्याहं न प्रणश्यामि स च मे न प्रणश्यति ||६-३०||
yo māṃ paśyati sarvatra sarvaṃ ca mayi paśyati . tasyāhaṃ na praṇaśyāmi sa ca me na praṇaśyati ||6-30||
6.30. He who observes Me in all and observes all in Me-for him I am not lost and he too is not lost for me.
Shri Purohit Swami
6.30 He who sees Me in everything and everything in Me, him shall I never forsake, nor shall he lose Me.
Sri Abhinav Gupta
6.30 Yo Mam etc. Loss : i.e., on account of serving no purpose [on the part of a thing]. For example : He who does not see the all-pervasive nature of the Supreme Self, from him the Supreme Self has fled away, because It does not reveal Its own nature. Further, this aggregate of objects, which is being perceived, remains settled down in the Supreme Self, which is the very nature of their illumination (being known). Now, whosoever fails to veiw the object as such, he gets lost from the naute of that Supreme Self. For, nothing shines without It. On the other hand, he who finds Me (the Supreme Consciousness) as immanent in all - for him I am not lost; because I appear [to him] in my own nature. [Again], when he perceives objects in Me-when his perceiverhood is complete on account of the possibility of illumination and manifestation of these objects due to This - then he is not lost for the Supreme Self.
6.30 (ii) He who, having reached the highest stage of maturity, views similarity of nature with Me, i.e., sees similarity of all selves to Myself when They are freed from good and evil and when they remain in Their own essence, as declared in the Sruti, ‘Stainless he attains supreme degree of eality’ (Mun. U., 3.1.3); and ‘sees Me in all selves and sees all selves in Me.’ That is, on viewing one of Them (selves), one views another also to be the same, because of their similarity to one another. To him who perceives the nature of his own self, I am not lost on account of My similarity to him i.e., I do not become invisible to him. He (the Yogin) viewing his own self as similar to Me, always remains within My sight when I am viewing Myself, because of similarity of his self with Me.
Sri Krsna describes a still more mature steps (of Yoga):
6.30 Yah, one who; pasyati, sees; mam, Me, Vasudeva, who am the Self of all; sarvatra, in all things; ca, and; sees sarvam, all things, all created things, beginning from Brahma; mayi, in Me who am the Self of all;-aham, I who am God; na pranasyami, do not go out; tasya,of his vision-of one who has thus realized the unity of the Self; ca sah, and he also; na pranasyati, is not lost; me, to My vision. That man of realization does not get lost to Me, to Vasudeva, because of the indentity between him and Me, for that which is called one’s own Self is surely dear to one, and since it is I alone who am the seer of the unity of the Self in all.
6.30 To him who sees Me in every self and sees every self in Me - I am not lost to him and he is not lost to Me.
6.30 One who sees Me in everything, and sees all things in Me-I do not out of his vision, and he also is not lost to My vision.
6.30 He who sees Me everywhere and sees everything in Me, he never becomes separated from Me, nor do I become separated from him.
6.30 यः who? माम् Me? पश्यति sees? सर्वत्र everywhere? सर्वम् all? च and? मयि in Me? पश्यति sees? तस्य of him? अहम् I? न not? प्रणश्यामि vanish? सः he? च and? मे to Me? न not? प्रणश्यति vanishes.Commentary In this verse the Lord describes the effect of the vision of the unity of the Self or oneness.He who sees Me? the Self of all? in all beings? and everything (from Brahma the Creator down to the blade of grass) in Me? I am not lost to him? nor is he lost to Me. I and the sage or seer of unity of the Self become identical or one and the same. I never leave his presence nor does he leave My presence. I never lose hold of him nor does he lose hold of Me. I dwell in him and he dwells in Me.
