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
Menurut tertibnya, tempoh aśauca ialah enam malam, atau tiga malam, atau satu malam—bagi Vaiśya, Kṣatriya dan Vipra (Brāhmaṇa) masing-masing. Adapun bagi Śūdra, aśauca diakui sekadar menurut ketetapan, dengan amalan yang paling minimum sebagaimana diajarkan.
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.
