Matsya Purana — Characteristics of Dvāpara and Kali Yugas
स्थाविर्ये मध्यकौमारे म्रियन्ते च कलौ प्रजाः अल्पतेजोबलाः पापा महाकोपा ह्यधार्मिकाः //
sthāvirye madhyakaumāre mriyante ca kalau prajāḥ alpatejobalāḥ pāpā mahākopā hyadhārmikāḥ //
In the Kali age, people die both in old age and in the midst of youth; they are of little radiance and strength, sinful, prone to great anger, and devoid of dharma.
This verse is not about cosmic pralaya; it describes social and moral deterioration in Kali-yuga—shortened vitality, increased sin, anger, and loss of dharma among people.
By portraying subjects as weak, irritable, and adharmic in Kali-yuga, it implies that kings and householders must actively uphold dharma—through self-restraint, just governance, ethical livelihood, and curbing anger and vice—to stabilize society.
No direct Vāstu or ritual procedure is stated; the takeaway is contextual—ritual discipline and dharmic conduct are presented as remedies for Kali-yuga’s moral volatility.
