Primary Rasa: shanta
Secondary Rasa: none
It highlights that Dharma is supported by precision: correct measurement and accepted standards safeguard ritual order, which in turn steadies the mind for Moksha-oriented discipline.
Indirectly: Bhakti in the Purana is not opposed to method; careful, rule-based practice (when worship involves rites) is presented as a way to offer worship without negligence.
Practical measurement and computation—using aṅgula-based units and an accepted approximation for relating diameter and circumference—knowledge akin to Śulba/kalpa-style technical procedure used in ritual settings.
