kalpa-vyatikarāmbhasā
loka-saṁsthāna-vijñāna
ātmanaḥ parikhidyataḥ
tam āhāgādhayā vācā

The Lord saw that Brahmā was very anxious about the planning and construction of the different planetary systems and was depressed upon seeing the devastating water. He could understand the intention of Brahmā, and thus He spoke in deep, thoughtful words, removing all the illusion that had arisen.
