Ābhūta-saṃplava & Loka-vibhāga
Dissolution Threshold and the Fourteen Abodes
ऋभुः सनत्कुमाराद्या यत्रासन्नूर्द्ध्वरेतसः / तपसा भावितात्मानस्तत्र संतीति वा तपः
ṛbhuḥ sanatkumārādyā yatrāsannūrddhvaretasaḥ / tapasā bhāvitātmānastatra saṃtīti vā tapaḥ
Where Ṛbhu, Sanatkumāra and the rest—ascetics of uplifted continence—abided, there dwelt souls refined by tapas; thus that place is spoken of as the realm of austerity.
