Who is speaking and story frame
तमेवान्वपिधीयन्ते लोको भूरादयस्त्रय: ।
निशायामनुवृत्तायां निर्मुक्तशशिभास्करम् ॥ २९ ॥
tam evānv api dhīyante
lokā bhūr-ādayas trayaḥ
niśāyām anuvṛttāyāṁ
nirmukta-śaśi-bhāskaram
When the night of Brahmā ensues, all the three worlds are out of sight, and the sun and the moon are without glare, just as in the due course of an ordinary night.
