Adhyaya 84: शिवव्रतकथनम्
Uma–Maheshvara Vrata, Shula-dana, and Month-wise Ekabhakta Vrata
व्रतं सुविपुलं पुण्यं नन्दिना परिभाषितम् मार्गशीर्षकमासे ऽथ वृषं पूर्णाङ्गमुत्तमम्
vrataṃ suvipulaṃ puṇyaṃ nandinā paribhāṣitam mārgaśīrṣakamāse 'tha vṛṣaṃ pūrṇāṅgamuttamam
قد شرح ناندين نذرًا مقدّسًا (vrata) واسعًا عظيمَ الثواب. ثم في شهر مارجشيرشا (Mārgaśīrṣa) ينبغي أن تُقدَّم ثورٌ ممتازٌ كاملُ الأعضاء—عطيّةٌ مباركةٌ توافق عبادةَ شِيفا—لكي يتقدّم الباشو (paśu)، أي الروح المقيَّدة، نحو نعمةِ الربّ، البَتي (Pati).
Suta Goswami (narrating Nandin’s injunctions within the discourse)
It links Liṅga-pūjā with a specific Shaiva vrata taught by Nandin and prescribes vṛṣa-dāna (gift of a flawless bull) in Mārgaśīrṣa as a high-merit act supporting Śiva’s worship.
Śiva is implied as Pati—the Lord who receives worship through disciplined vrata and purifying gifts; such acts are presented as means for the paśu (individual soul) to become fit for Śiva’s grace and release from pāśa (bondage).
A Shaiva vrata (regulated observance) combined with dāna—specifically offering a fully healthy bull in Mārgaśīrṣa—functioning as a purificatory discipline supportive of Pāśupata-oriented devotion.
