I've read this answer in which lord krishna say "I m the light of sun and moon" which is justify in grammatical way.
But I've read another verse , in which lord krishna said Tejah from the sun is from me, and tejah from the moon is also from me.
यदादित्यगतं तेजो जगद्भासयतेऽखिलम् । यच्चन्द्रमसि यच्चाग्नौ तत्तेजो विद्धि मामकम्
The splendor of the sun, which dissipates the darkness of this whole world, comes from Me. And the splendor of the moon and the splendor of fire are also from Me.
Chapter 15 : Verse 12
Here tejah means splender according to bhagwad gita as it is. But in sanskrit tejah means light. (Particulary light from the sun).
So can someone please help me to understand this verse? Since moon doesn't light itself.
