As this Yuga passes on, virtue becomes daily weaker. As virtue becomes weak, all creatures degenerate. And as creatures degenerate. their nature also undergoes deterioration. The religious acts performed at this waning of the Yuga produce contrary effects. Even those who live for several Yugas must conform to their changes.
युगेष्वावर्तमानेषुधर्मो व्यावर्तते पुनः। धर्मे व्यावर्तमाने तु लोको व्यावर्तते पुनः॥ लोके क्षीणे क्षयं यान्ति भावा लोकप्रवर्तकाः। युगक्षयकृताधर्माः प्रार्थनानि विकुर्वते॥ एतत् कलियुगं नाम अचिराद् यत् प्रवर्तते। युगानुवर्तनं त्वेतत् कुर्वन्ति चिरजीविनः॥
