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.

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.
