It emphasizes that ritual acts gain sanctity through right procedure (ācāra): timely invitation and the moral-spiritual fitness of the officiant, especially self-restraint and brahmacarya.
By insisting on purity of conduct and disciplined senses in those serving sacred acts, it supports bhakti as disciplined worship—devotion is strengthened when offerings and services are performed with inner restraint and reverence.
Kalpa (ritual procedure) is implied: formal invitation (nimantraṇa), correct timing, and qualification of the priest/participant are practical rules that preserve the correctness of rites.
