Even in a Mokṣa-dharma setting, the Purāṇa preserves disciplined pramāṇa (right measure): it teaches that correct action requires removing what is “non-admissible” and proceeding with a purified, net remainder—an ethical analogue of inner purification.
Indirectly: it models careful, rule-based offering and preparation. In Bhakti, offerings and ritual supports are done with accuracy and integrity—taking only what is grāhya (fit) and rejecting what is unfit—so devotion is expressed through disciplined conduct.
Pramāṇa and applied computation (māna): a procedural formula using halves, exclusions (varjita), and a fixed fraction (1/60) scaled by ten—typical of technical instructions used in ritual preparation and allied Vedic sciences.
