FAQs
Indirectly: by defining vast, ordered cycles of time (kāla) within which beings experience Dharma and its changes, the verse supports the Purāṇic view that the unchanging Self stands apart from time while the cosmos moves through measured epochs.
No specific practice is taught in this verse; it provides the kāla-framework (yuga and its sandhyā periods) that later supports Kurma Purana’s discipline-oriented teachings—where sādhanā, austerity, and Dharma are aligned with the conditions of each age.
It does not explicitly mention Śiva or Viṣṇu; however, as a shared Purāṇic cosmology, the measured order of time is presented as a universal doctrine compatible with the Kurma Purana’s Shaiva–Vaishnava synthesis in other sections.
