Ābhūta-saṃplava & Loka-vibhāga
Dissolution Threshold and the Fourteen Abodes
अवीचिर्दारुणः प्रोक्तो यन्त्रसंपीडनाच्च सः / तस्मात्सुदारुणो लोहः कर्मणां श्रयणाच्च सः
avīcirdāruṇaḥ prokto yantrasaṃpīḍanācca saḥ / tasmātsudāruṇo lohaḥ karmaṇāṃ śrayaṇācca saḥ
Avīci is declared dreadful, for there one is crushed by tormenting devices. Therefore Loha is most dreadful too, since it is the support and consequence of one’s karmic deeds.
