रुद्रावृत्त्याखिलर्द्धिश्च तदायत्तं जगद्भवेत् । अर्कावृत्त्या सिद्धिभिः स्याद्दिग्भिर्मर्त्यो हरोपमः ॥ १७३ ॥

రుద్రవృత్తిని ఆచరించుటవలన సమస్త సమృద్ధి లభించి, జగత్తు అతని ఆధీనమగును. అర్కవృత్తిని ఆచరించుటవలన మానవుడు సిద్ధులతో యుక్తుడై, దిక్కులపై ఆధిపత్యముతో హరుడు (శివుడు) సమానుడగును.

It teaches that adopting specific divine-aligned disciplines (vṛtti)—here associated with Rudra and the Sun—produces corresponding results: prosperity, influence, siddhis, and an elevated, Śiva-like stature.
Bhakti is implied as disciplined alignment with a deity’s principle: living or practicing in a Rudra- or Surya-oriented way (through vrata, mantra, and regulated conduct) is presented as a means to divine grace and transformative power.
The verse reflects a technical linkage between practice and result—typical of Vedāṅga-style application—especially the Surya/Arka theme often connected with jyotiṣa (astral-directions, dig-related strength) and disciplined observances yielding siddhi.
