Kāla-vibhāga: The Divisions of Time from Atom to Brahmā, and the Lord Beyond Time
तमेवान्वपिधीयन्ते लोको भूरादयस्त्रय: । निशायामनुवृत्तायां निर्मुक्तशशिभास्करम् ॥ २९ ॥
tam evānv api dhīyante lokā bhūr-ādayas trayaḥ niśāyām anuvṛttāyāṁ nirmukta-śaśi-bhāskaram
ពេលរាត្រីរបស់ព្រះព្រហ្មមកដល់ ពិភពទាំងបី—ភូរ ជាដើម—លាក់បាត់ពីទស្សនៈ ហើយពន្លឺព្រះអាទិត្យនិងព្រះចន្ទក៏រលត់ ដូចរាត្រីធម្មតា។
It is understood that the glare of the sun and moon disappear from the sphere of the three worlds, but the sun and the moon themselves do not vanish. They appear in the remaining portion of the universe, which is beyond the sphere of the three worlds. The portion in dissolution remains without sun rays or moonglow. It all remains dark and full of water, and there are indefatigable winds, as explained in the following verses.
This verse states that the three worlds beginning with Bhūḥ are enveloped when night prevails, described as a condition where the light of the Sun and Moon is absent.
In this chapter he is teaching Parīkṣit Mahārāja the workings of kāla (time) and cosmic cycles; describing night and the covering of the worlds illustrates how the universe is governed by time’s rhythms.
Remembering that everything moves under time’s control helps cultivate detachment, humility, and steadiness in bhakti—using one’s limited time for sādhana and remembrance of the Lord.
