Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
यस्त्वेकभक्तेन समां शिवं हैमवृषान्वितम् धेनुं तिलमयीं दद्यात् स पदं याति शांकरम् एतद्रुद्रव्रतं नाम पापशोकविनाशनम् //
yastvekabhaktena samāṃ śivaṃ haimavṛṣānvitam dhenuṃ tilamayīṃ dadyāt sa padaṃ yāti śāṃkaram etadrudravrataṃ nāma pāpaśokavināśanam //
Whoever, with single-minded devotion, offers a sesame-made cow (dhenu-dāna) together with an image of Śiva accompanied by a golden bull, attains the abode of Śaṅkara. This is called the Rudra-vrata, the vow that destroys sin and sorrow.
This verse does not discuss pralaya; it focuses on ritual merit (vrata) and dāna as a means to remove sin and sorrow and to reach Śiva’s abode.
It presents a practical householder/royal duty: sanctioned giving (dāna) with focused devotion. Such gifts—especially symbolically potent offerings like dhenu-dāna—are framed as dharmic acts that purify one’s life and secure auspicious posthumous attainments.
Ritually, it specifies a Śaiva vow involving icon-linked gifting: an image of Śiva with a golden bull emblem and a sesame-formed cow offering. The emphasis is on correct ritual components (materials and associated symbols) rather than temple architecture.
