Gita 13.31 Meaning: - The meaning of Verse 31 is that just as sun even when situated far away is visible in a pot of water and keeps influencing us with his formless power i.e. warmth. Similarly, the Supreme God even when residing in Satyalok dwells in every soul in the form of shadow. Like the radiations of sun produce excessive heat on a concave lens and keeps its natural influence on a convex lens. Similarly, a devotee who is in accordance with the scriptures becomes a concave lens, by which he obtains maximum benefit of God’s power. And a devotee, who follows arbitrary way of worship by abandoning the injunctions of scriptures, only obtains the results of his actions. Consider him to be a convex lens.
