||constitute a day and night of mortals: thirty such days make a month, divided into two half months: six months form an Ayana (the period of the sun s progress north or south of the ecliptic): and two Ayanas compose a year. The southern Ayana is a night, and the northern a day of the gods. Twelve thousand divine years, each composed of (three hundred and sixty) such days, constitute the period of the four Yugas, or ages. They are thus distributed: the Krita age has four thousand divine years; the Treta three thousand; the Dwapara two thousand; and the Kali age one thousand: so those acquainted with antiquity have declared. The period that precedes a Yuga is called a Sandhya, and it is of as many hundred years as there are thousands in the Yuga: and the period that follows a Yuga, termed the Sandhyansa, is of similar duration. The interval between the Sandhya and the Sandhyansa is the Yuga, denominated Krita, Treta, &c. The Krita, Treta, Dwapara, and Kali, constitute a great age, or aggregate of four ages: a thousand such aggregates are a day of Brahma, and fourteen Manus reign within that term.
