व्यपोहनस्तवनिरूपण-प्रसङ्गे नक्तभोजन-शिवव्रतविधिः (वार्षिक-प्रतिमास-क्रमः)
तानि व्यासादुपश्रुत्य युष्माकं प्रवदाम्यहम् अष्टम्यां च चतुर्दश्यां पक्षयोरुभयोरपि
tāni vyāsādupaśrutya yuṣmākaṃ pravadāmyaham aṣṭamyāṃ ca caturdaśyāṃ pakṣayorubhayorapi
Having heard those teachings from Vyāsa, I now declare them to you: the observances to be performed on the Eighth (Aṣṭamī) and on the Fourteenth (Caturdaśī) lunar days, in both fortnights—bright and dark—for the worship of Śiva and for the loosening of the paśu’s bonds (pāśa) by the grace of Pati, the Lord.
Suta Goswami
It authorizes specific Shiva-centered observances on Aṣṭamī and Caturdaśī in both fortnights, framing them as a received tradition (from Vyāsa) and a practical schedule for regular Liṅga-pūjā.
By implying Shiva as Pati—the Lord whose worship is regulated by sacred time (tithi)—the verse positions him as the liberating principle who can loosen pāśa (bondage) for the paśu (individual soul) through disciplined observance.
Tithi-based vrata discipline: undertaking Shiva observances specifically on the 8th and 14th lunar days in both pakṣas, a common Shaiva framework supporting steady pūjā and Pāśupata-oriented self-restraint.
