It teaches that spiritual merit becomes “akṣaya” (unfailing) when vows are performed with correct timing (tithi) and in accordance with Smṛti-based dharma.

It highlights calendrical/astronomical calculation used in ritual timing—tithi determination (a Jyotiṣa-linked practical skill) applied to Dharmaśāstra/Smṛti observances.
