Matsya Purana — Pṛthu
दोग्धा बृहस्पतिरभूत् पात्रं वेदस्तपो रसः देवैश्च वसुधा दुग्धा दोग्धा मित्रस्तदाभवत् //
dogdhā bṛhaspatirabhūt pātraṃ vedastapo rasaḥ devaiśca vasudhā dugdhā dogdhā mitrastadābhavat //
Bṛhaspati became the milker, and the vessel was the Veda—its essence being the rasa born of tapas (austerity). Thus the gods milked the Earth; and at that time Mitra also became the milker.
It reflects a creation-era symbolism: the Earth is ‘milked’ to yield sustenance and essences for beings. Rather than Pralaya, it emphasizes ordered manifestation—cosmic resources arising through sacred knowledge (Veda) and spiritual heat (tapas).
By analogy, rulers and householders should ‘draw’ wealth and resources through dharmic means—guided by śāstra (like the Veda as a vessel) and disciplined effort (tapas), not by exploitation. Prosperity is portrayed as legitimate when extracted with order and restraint.
Ritually, it elevates Veda and tapas as the ‘containers’ of effective sacred action—implying that yajña and consecrations succeed when grounded in scriptural procedure and disciplined purity, a principle later echoed in Vastu/temple rites even if not explicitly architectural here.
