tri-lokyām - when the spheres of the three worlds; dahyamānāyām - being set ablaze; śaktyā - by the potency; saṅkarṣaṇa - from the mouth of Saṅkarṣaṇa; agninā - by the fire; yānti - they go; ūṣmaṇā - heated by the warmth; mahaḥ-lokāt - from Maharloka; janam - to Janaloka; bhṛgu - the sage Bhṛgu; ādayaḥ - and others; arditāḥ - being so distressed.

The devastation takes place due to the fire emanating from the mouth of Saṅkarṣaṇa, and thus great sages like Bhṛgu and other inhabitants of Maharloka transport themselves to Janaloka, being distressed by the warmth of the blazing fire which rages through the three worlds below.
