It has been said that the Day came first. Then came Night. The Months are said to have the lighted fortnights first. The constellations have Shravana for their first; the Seasons have that of dews (viz., Winter) for their first.
अहः पूर्वं ततो रात्रिर्मासाः शुक्लादयः स्मृताः। श्रवणादीनि ऋक्षाणि ऋतवः शिशिरादयः॥
