māsaḥ pakṣadvayenokto dvau māsau cārkajāv ṛtuḥ ṛtutrayaṃ cāpy ayanaṃ dve 'yane varṣasaṃjñite
A month is declared to consist of two pakṣas. Two months make a season (ṛtu), born of the Sun’s course. Three seasons form an ayana (half-year), and the two ayanas together are known as a year.
Sage Parāśara (teaching Maitreya)
Speaker: Parasara
Topic: Hierarchical construction of calendrical time: pakṣa → māsa → ṛtu → ayana → varṣa
Teaching: Cosmological
Quality: authoritative
Concept: Time is built in nested cycles—from fortnights to months, seasons, half-years, and the full year—grounded in the Sun’s movement.
Vedantic Theme: Dharma
Application: Plan spiritual goals in layered horizons (daily/fortnightly/seasonal/annual), using cyclical review to sustain long-term sādhanā.
Vishishtadvaita: The Sun’s ordered course, integral to dharma and ritual timing, reflects a cosmos fit for devotion and governed by a unifying principle.
This verse shows time as a structured cosmic order—month, season, ayana, and year—grounded in the Sun’s course, reflecting a universe governed by intelligible law.
He defines a month as two fortnights, a season as two months, an ayana as three seasons, and the year as the union of two ayana-s—building a clear hierarchical model of time.
Even when speaking of solar and calendrical cycles, the Purāṇa’s cosmology frames such order as part of the divinely sustained universe—time’s regularity ultimately pointing to Vishnu’s sovereign maintenance of creation.
