Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
शून्येषु लोकस्थानेषु महान्तेषु भुवादिषु / देवेषु च गतेष्वूर्द्ध्वं सायुज्यं कल्पवासिनाम्
śūnyeṣu lokasthāneṣu mahānteṣu bhuvādiṣu / deveṣu ca gateṣvūrddhvaṃ sāyujyaṃ kalpavāsinām
When the great abodes of the worlds—Bhu and the rest—stand empty, and the Devas have gone upward, the dwellers of the Kalpa attain sāyujya, the supreme union.
