Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
शाकद्वीपादिषु ज्ञेयं पञ्चस्वेतेषु सर्वशः देशस्य तु विचारेण कालः स्वाभाविकः स्मृतः //
śākadvīpādiṣu jñeyaṃ pañcasveteṣu sarvaśaḥ deśasya tu vicāreṇa kālaḥ svābhāvikaḥ smṛtaḥ //
In Śākadvīpa and the other regions, throughout all these five divisions, one should understand that time is regarded as “natural”—that is, determined according to a considered assessment of the locality.
It does not speak directly about Pralaya; it teaches that ‘time’ (kāla) used for decisions is to be treated as natural and place-dependent, emphasizing cosmic order expressed through regional conditions.
It implies that a king or householder should set rituals, festivals, and administrative timing after evaluating local conditions (deśa-vicāra), rather than applying a single uniform standard everywhere.
For Vāstu and rites, it supports choosing auspicious timings and procedures in harmony with the locality—climate, seasonality, and regional norms—treating kāla as ‘svābhāvika’ (inherent to the place).
