15.12. That light which is found in the sun, which is in the moon, and which is [also] in the fire-all illuminating the entire world-know that light to be of Mine.

Shri Purohit Swami

15.12 Remember that the Light which, proceeding from the sun, illumines the whole world, and the Light which is in the moon, and That which is in the fire also, all are born of Me.

Sri Abhinav Gupta

15.12 See Comment under 15.14

Sri Ramanuja

15.12 That brilliance of the sun and other luminaries which illumines the whole universe - that brilliance belongs to Me. Know that this capacity of illumining is granted to them by Me who have been worshipped severally by them.

Sri Krsna states that the power in the earth to support all those that reside on it belongs to Him alone:

Sri Shankaracharya

15.12 Yat, that which is; aditya-gatam, in the sun, which abides in the sun;-what is that-the tejah, light, brilliance, radiance; which bhasayate, illumines, reveals; akhilam, the whole, entire; jagat, world; yat, that ulluminating light which is; candramasi, in the moon; ca, and yat, which is; agnau, in fire, the carrier of oblations; viddhi, know; tat, that; tejah, light; to be mamakam, Mine. That light belong to Me who am Visnu. Or: The light that is Consciousness, which is in the sun, which is in the moon, and which is in fire, know that light to be Mine. That light belongs to Me who am Visnu. Objection; Is it not that the light that is Consciousness exists eally in the moving and the non-moving? Such being the case, why is this particular mention, ‘That light in the sun which৷৷.,’etc? Reply: This defect does not arise, because, owing to the abundance of the sattva ality, there can be an abundane [Ast. reads avistaratva (amplitude) in place of adhikya.-Tr.] (of Consciousness). Since in the sun etc. the sattva is very much in evidence, is greatly brilliant, therefore there is an abundance of the light (of Consciousness) in them alone. And so it (sun etc.) is specially mentioned. But it is not that it (Consciousness) is abundant only there. Indeed, as in the world, a face, though in the same position, is not reflected in wood, a wall, etc., but in a mirror etc. it is reflected according to the degree in which they are more and more transparent, so is it here. Further,

15.12 That brilliance in the sun which illumines the whole universe, that in the moon and that in fire, know that brilliance as Mine.

Swami Gambirananda

15.12 That light in the sun which illumines the whole world, that which is in the moon, and that which is in fire,-know that light to be Mine.

Swami Sivananda

15.12 That light which residing in the sun illumines the whole world, that which is in the moon and in the fire know that light to be Mine.


Swami Sivananda

15.12 यत् which? आदित्यगतम् residing in the sun? तेजः light? जगत् the world? भासयते illumines? अखिलम् whole? यत् which? चन्द्रमसि in the moon? यत् which? च and? अग्नौ in the fire? तत् that? तेजः light? विद्धि know? मामकम् Mine.Commentary The immanence of the Lord as the allilluminating light of consciousness is described in this verse.I am the cause and the source of the light by which the sun illumines the world? as also the reflected light of the sun in the moon and that of fire.Tejah Light The light of consciousness.If that is so? an objector says The light of consciousness exists alike in all moving and unmoving objects. Then why has the Lord mentioned this special alification of light as residing in the sun? moon and fire Please explain. We say The higher manifestation of the light of consciousness in the sun? etc.? is due to a large concentration of Sattva in them. Sattva is very brilliant and luminous in them. That is the reason why there is this special alification.Here is an illustration. The face of a man is not at all reflected on a wall? piece of wood or a block of stone? but the same face is reflected beautifully in a very clean mirror. The degree of clearness of the reflection in the mirror is acording to the degree of transparency of the mirror. The more the transparency of the mirror? the better the reflection of the face the less the transparency? the worse the reflection. Even so Gods light shines in the sun and also in the pure heart of a devotee.
