तच्छेषश्च त्रिगुणितः तेनैवाप्तं दिनानि च । शेषे षष्ट्या हते भक्ते हारेण घटिकादिकम् ॥ १२७ ॥

يُضرب ذلك الباقي في ثلاثة، وبه يُستخرج عددُ الأيام. ثم من الباقي المتبقّي، إذا ضُرب في ستين وقُسِم على المقسوم عليه، حُصِل على الغَṭيكَا (ghaṭikā) وما دونها من أجزاء الزمان.

It shows that Dharma-practice is supported by precision: correct time-reckoning (kāla-nirṇaya) safeguards ritual order and discipline, which in turn steadies the mind for Moksha-oriented living.
Indirectly: Bhakti is strengthened when worship and vows are performed at properly determined times; this verse supplies the practical method to compute days and ghaṭikās so devotional observances are done correctly.
Vedāṅga Jyotiṣa (astronomical/chronological computation): using remainders, multiplication by 3 and 60, and division to derive days and ghaṭikā units for calendrical and ritual timing.
