FAQs
This verse does not directly define Ātman; it frames dharma through rules of adhikāra (eligibility) and ritual boundaries, which the Kurma Purana treats as preparatory discipline that stabilizes conduct before higher spiritual instruction.
No explicit yoga technique is taught here; the emphasis is on ethical-ritual restraint (niyama-like discipline) and guarding sacred instruction and sacrificial substances, which the tradition presents as supportive foundations for later yoga and devotion.
It does not explicitly address Śiva–Viṣṇu unity; it belongs to the dharma section of the Purva-bhāga, which sets social-ritual norms that later culminate—especially in the Upari-bhāga’s Ishvara Gītā—in more universal spiritual synthesis.
