FAQs
Indirectly: it treats purity as a preparatory discipline (śauca) for dharma and inner clarity; the Self is unstained, but the practitioner observes āśauca–snāna rules to steady conduct and mind for higher knowledge.
Śauca (cleanliness) as a niyama-like discipline: after the impurity-period ends, one performs snāna to restore ritual fitness, supporting steadiness for mantra, worship, and yogic practice emphasized elsewhere in the Kurma Purana.
Not explicitly; it reflects the shared dharma framework honored across Shaiva–Vaishnava traditions in the Kurma Purana, where outer discipline (purity rules) supports inner devotion and realization regardless of iṣṭa-devatā.
