Adhyaya 52: सोमाधारः, पुण्योदानदी, मेरुप्रदक्षिणा, जम्बूद्वीपनववर्षवर्णनम्
त्रयोदशसहस्राणि शतानि दशपञ्च च जीवन्ति ते महावीर्या न चान्यस्त्रीनिषेविणः
trayodaśasahasrāṇi śatāni daśapañca ca jīvanti te mahāvīryā na cānyastrīniṣeviṇaḥ
その大いなる威力を備えた者たちは一万三千百十五年を生き、他の女と交わることがない。
Suta Goswami
It links longevity and spiritual power (mahāvīrya) with disciplined conduct; such restraint supports steady Linga-upāsanā by preserving focus, purity, and tapas for approaching Pati (Shiva).
By implication, Shiva-tattva is approached through mastery of desire and conservation of inner potency; the pashu becomes fit to receive Shiva’s grace when pasha—especially sense-bondage—is weakened by restraint.
Brahmacarya as a core limb of tapas within a Pāśupata-oriented discipline—restraint of sexual indulgence to stabilize prāṇa and strengthen sādhana.
