दन्तोलूखलिनः केचिदश्मकुट्टास्तथा परे । पञ्चाग्निसाधकाश्चान्ये सद्यः प्रक्षालकास्तथा
dantolūkhalinaḥ kecidaśmakuṭṭāstathā pare | pañcāgnisādhakāścānye sadyaḥ prakṣālakāstathā
كان بعضهم يمارس رياضاتٍ شديدة كالسَّحق بالأسنان كأنها مِهراس، وآخرون يدقّون الحجر. ومنهم من يؤدي توبة «البنجاغني» (نار الخمس)، ومنهم من يلازم الاغتسال التطهيري الفوري—وهكذا انشغلوا بتابَسٍ قاسٍ.
Narrator (contextual; likely Sūta continuing the account)
Tirtha: Arbuda (tapas-sthāna)
Type: kshetra
Scene: Multiple ascetics in distinct penances: one clenches and grinds as if using teeth as a mortar (dantolūkhalin), another pounds stone (aśma-kuṭṭa), another sits amid four fires with the sun overhead (pañcāgni), while others repeatedly wash at a nearby water source, all on a rugged mountain setting.
Steadfast tapas and self-purification, when done with devotion, draws divine grace and protection.
The passage is within Arbuda Khaṇḍa and leads toward the Nāgahrada-tīrtha glorification later in the chapter.
Pañcāgni-sādhana (five-fire austerity) and acts of immediate purification/cleansing are referenced.
