Explanation
Krishna moves from metaphysics to daily recognition. Every experience of light can become a remembrance of Him: sunlight, moonlight, fire, warmth, visibility, and clarity.
Read the traditional commentary
Having described the Supreme as a self-luminous abode in verse 6, Krishna now turns to show His radiance pervading the world we already know. The light of the sun that illuminates the entire universe, the gentle glow of the moon, the brightness of fire — all of these, He says, are His own tejas, His divine splendor.
The luminaries we depend on are not independent sources; they are vessels through which the one supreme light shines.
This teaching transforms ordinary experience into worship. Every time we feel the warmth of sunlight, walk by moonlight, or sit before a flame, we are encountering a reflection of the Divine. Krishna is teaching the seeker to read the visible world as a continuous revelation of the invisible Lord.
The world is not separate from God; it is shot through with His presence. To know this is to live in constant remembrance, finding the sacred not only in meditation but in the very light that fills our days.
In daily life
Use natural light as a Krishna-remembrance cue.
