Adhyaya 84: शिवव्रतकथनम्
Uma–Maheshvara Vrata, Shula-dana, and Month-wise Ekabhakta Vrata
स याति शिवसायुज्यं नारी देव्या यदि प्रभो अष्टम्यां च चतुर्दश्यां नियता ब्रह्मचारिणी
sa yāti śivasāyujyaṃ nārī devyā yadi prabho aṣṭamyāṃ ca caturdaśyāṃ niyatā brahmacāriṇī
হে প্ৰভো! যি নাৰী দেৱীৰ ভক্তিত নিয়ত হৈ সংযমসহ ব্ৰহ্মচৰ্য পালন কৰে আৰু অষ্টমী আৰু চতুৰ্দশী তিথিত নিয়মপৰায়ণা থাকে, সি শিৱ-সায়ুজ্য লাভ কৰে।
Suta Goswami (narrating the vrata-phala within the Linga Purana discourse)
It links Shiva-realization (śiva-sāyujya) to vrata-based discipline—especially observing Aṣṭamī and Caturdaśī with restraint—showing that worship is not only external (liṅga-pūjā) but also internal purification through niyama.
Shiva is implied as Pati, the liberating Lord, attainable through sāyujya—an intimate mode of liberation—when the pashu (individual soul) weakens pasha (bondage) via disciplined conduct and devotion aligned with Śiva-Śakti.
Tithi-vrata on Aṣṭamī and Caturdaśī combined with brahmacarya and niyama—an ascetic-ethical practice that parallels Shaiva sādhanā (including Pāśupata-style restraint) as a means to spiritual fruition.
