Matsya Purana — The Rite of the Jaggery-Cow
उत्तमा गुडधेनुः स्यात् सदा भारचतुष्टयम् वत्सं भारेण कुर्वीत द्वाभ्यां वै मध्यमा स्मृता //
uttamā guḍadhenuḥ syāt sadā bhāracatuṣṭayam vatsaṃ bhāreṇa kurvīta dvābhyāṃ vai madhyamā smṛtā //
The finest “jaggery-cow” (guḍa-dhenū) should always weigh four bhāras. Its calf should be fashioned with one bhāra; the medium grade is remembered as two bhāras.
Nothing directly—this verse is a technical rule from dāna-dharma, specifying the standard weights for a ritual “jaggery-cow” gift rather than cosmology or pralaya.
It gives a concrete dāna procedure: householders (and kings performing public charity) should follow prescribed standards—here, the weight-grades of a guḍa-dhenū and its calf—so the gift is ritually valid and proportionate.
Ritually, it defines measurable specifications (bhāra-based grades) for constructing a symbolic donation item (guḍa-dhenū with a calf), reflecting the Purāṇic emphasis on exact proportions and standardized measures in rites.
