Arjuna meets the Lokapālas, is tested by Indra, and is led to Amarāvatī for astra-śikṣā
Indraloka-gamana
स मासान् विभजन् काले बहुथधा पर्वसंधिषु । तथैव भगवान् सोमो नक्षत्र: सह गच्छति,“उसी प्रकार भगवान् चन्द्रमा भी नक्षत्रोंके साथ मेरु पर्वतकी परिक्रमा करते हैं और पर्वसंधिके समय विभिन्न मासोंका विभाग करते रहते हैं
sa māsān vibhajan kāle bahudhā parva-sandhiṣu | tathaiva bhagavān somo nakṣatraiḥ saha gacchati ||
Dijo Vaiśampāyana: «Así, con el debido transcurso del tiempo, en las junturas de las estaciones, los meses se reparten de muchas maneras. Del mismo modo, el divino Soma, la Luna, avanza junto con las constelaciones, hace su circuito en torno a Meru y, con ello, señala las divisiones de los meses.»
वैशम्पायन उवाच
The verse highlights ṛta/dharma as cosmic regularity: time is not arbitrary but structured through observable celestial motions, especially the Moon’s progress with the nakṣatras, which underwrites the calendrical division of months and seasonal transitions.
Vaiśampāyana describes how months and seasonal junctures are determined, explaining that the Moon, moving in concert with the constellations (nakṣatras), serves as the celestial marker by which the divisions of time are recognized.
