कालनिर्णयः (युग-मन्वन्तर-कल्पप्रमाणम्) — Measures of Time and Cosmic Cycles
चतुर्युगाणां संख्याता साधिका ह्य् एकसप्ततिः मन्वन्तरं मनोः कालः सुरादीनां च सत्तम
caturyugāṇāṃ saṃkhyātā sādhikā hy ekasaptatiḥ manvantaraṃ manoḥ kālaḥ surādīnāṃ ca sattama
Seventy-one cycles of the four yugas, together with their junction-periods, are declared to be a Manvantara: the span of a Manu’s rule, and likewise the ordained measure of time for the gods and other celestial orders.
Sage Parāśara (teaching Maitreya)
Speaker: Parasara
Topic: Definition of Manvantara in terms of yuga-cycles and junction periods (sandhyā/sandhyāṃśa)
Teaching: Cosmological
Quality: precise
Creation Stage: Manvantara
Concept: A Manvantara equals seventy-one caturyuga cycles plus their junction periods, setting the ordained lifespan for Manu and the celestial orders.
Vedantic Theme: Dharma
Application: Use the idea of ‘sandhi’ (junctions) as a spiritual metaphor: attend carefully to transitions in life and practice (beginnings/endings) with heightened awareness.
Vishishtadvaita: Time is not random but a dharma-governed order sustained by the Supreme who measures and apportions lifespans and offices.
Vishnu Form: Para-Brahman
Bhakti Type: Shanta
Jagat Karana: Yes
This verse defines a Manvantara as 71 four-yuga cycles (with added junction periods), establishing the Purana’s key framework for cosmic history and governance under successive Manus.
He presents time as nested cycles: yugas form a caturyuga, and 71 such caturyugas (including transitional additions) form a Manvantara—the operative epoch for Manu and celestial beings.
By defining the lawful measure of cosmic time, the text implies an intelligible, divinely upheld order—ultimately grounded in Vishnu as the Supreme regulator of creation’s cycles.
