Sūta said:: There are six aspects to be mentioned in regard to the set of four Yugas. viz. Yuga, the difference of Yugas, Yugadharma (peculiar characteristics of the Yuga), Yuga-Sandhi, (the junction of Yugas), Yugāṃśāka (the part of the Yuga) and the Yugasandhāna (joints of two Yugas). I shall narrate these factually in details. I shall enumerate every thing and I shall indicate the exact number (where necessary).
