Aśauca-vidhi — Rules of Birth/Death Impurity, Sapinda Circles, and Śrāddha Sequence
षड्रात्रं वा त्रिरात्रं स्यादेकरात्रं क्रमेण हि / वैश्यक्षत्रियविप्राणां शूद्रेष्वाशौचमेव तु
ṣaḍrātraṃ vā trirātraṃ syādekarātraṃ krameṇa hi / vaiśyakṣatriyaviprāṇāṃ śūdreṣvāśaucameva tu
Sa wastong pagkakasunod, ang panahon ng aśauca ay anim na gabi, o tatlong gabi, o isang gabi—para sa Vaiśya, Kṣatriya, at Vipra (Brāhmaṇa), ayon sa pagkakasunod. Ngunit para sa Śūdra, kinikilala lamang ang aśauca ayon sa itinakdang pinakamaliit na pagtalima.
Sūta (narrator) conveying the Kurma Purana’s dharma-teaching in context
Primary Rasa: shanta
This verse is primarily a dharma-śāstra injunction on āśauca durations by varṇa; it does not directly teach ātman-metaphysics, but it supports the Purāṇic aim of inner purity through regulated conduct.
No specific yoga practice is taught here; the emphasis is on śauca/āśauca discipline, which functions as an ethical-ritual foundation that complements later Kurma Purana teachings on devotion and yogic restraint.
This verse does not explicitly discuss Śiva–Viṣṇu unity; it belongs to the dharma section. In the Kurma Purana’s broader synthesis, such dharma regulations are framed as supportive of devotion to the one Supreme (Hari-Hara) taught elsewhere.
