Matsya Purana — The Rite of the Jaggery-Cow
देहस्था या च रुद्राणी शंकरस्य सदा प्रिया धेनुरूपेण सा देवी मम पापं व्यपोहतु //
dehasthā yā ca rudrāṇī śaṃkarasya sadā priyā dhenurūpeṇa sā devī mama pāpaṃ vyapohatu //
May that Rudrāṇī—dwelling within the body, ever dear to Śaṅkara—she who appears in the form of the cow, remove my sin.
This verse is not about cosmic creation or pralaya; it is a protective devotional prayer (stuti) seeking the removal of personal sin through the grace of Rudrāṇī in a sacred, beneficent form.
It supports the householder/kingly ethic of maintaining purity and dharma through devotion and expiation: acknowledging pāpa and seeking its removal via sanctioned devotional recitation, aligning conduct with righteousness.
The ritual takeaway is stuti-japa/prayer as an expiatory act; the cow-form imagery highlights sanctity and protection (often linked with auspiciousness and purification), rather than temple architecture or Vāstu prescriptions.
