Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
तिलधेनुसमोपेतं समान्ते हेमपङ्कजम् शुद्धमष्टाङ्गुलं दद्याच् छिवलोके महीयते सामगाय ततश्चैतत् सामव्रतमिहोच्यते //
tiladhenusamopetaṃ samānte hemapaṅkajam śuddhamaṣṭāṅgulaṃ dadyāc chivaloke mahīyate sāmagāya tataścaitat sāmavratamihocyate //
Along with the gift of a “sesame-cow” (tiladhenu), at the conclusion of the observance one should also offer a pure golden lotus, eight aṅgulas in measure. Having done so, the chanter of the Sāma is honored in Śiva’s world; therefore this observance is here called the Sāma-vrata.
This verse does not address pralaya; it focuses on dāna (ritual gifting) connected to a Sāmavedic vow (Sāma-vrata) and the resulting merit in Śiva’s realm.
It frames a householder/kingly duty as patronage of Vedic specialists through correctly measured, ritually pure gifts (tiladhenu and a golden lotus), presenting charity as a dharmic means to gain spiritual merit and honor.
The ritual significance is precise prescription: the donor should give a pure golden lotus of eight aṅgulas at the rite’s conclusion, together with a tiladhenu—showing how Matsya Purana specifies measurements and accompaniments for effective vrata-related donations.
