12.4.12

paraḥ sāṃvartako vāti dhūmraṃ khaṃ rajasāvṛtam /
tato megha-kulāny aṅga citra varṇāny anekaśaḥ //

12. & 13. The sky remains hazy covered with dust; then for a century hosts of clouds, in various forms, pour down showers and peal thunders of terrible noise; thereupon the whole Universe is one sheet of water throughout the space within the egg of the Universe.
