Matsya Purana — Characteristics of Dvāpara and Kali Yugas
अधर्माभिनिवेशित्वं तमोवृत्तं कलौ स्मृतम् भ्रूणहत्या प्रजानां न तथा ह्येवं प्रवर्तते //
adharmābhiniveśitvaṃ tamovṛttaṃ kalau smṛtam bhrūṇahatyā prajānāṃ na tathā hyevaṃ pravartate //
In the age of Kali, the settled attachment to adharma is remembered as a dark, tamasic disposition. Even the killing of embryos among people is no longer treated or regarded as it should be—so pervasive is this tendency.
This verse is not about Pralaya; it characterizes Kali-yuga as an age where tamasic attachment to adharma becomes socially entrenched.
It implies that rulers and householders must actively restrain tamasic, adharma-driven social behavior through dharmic governance, education, and personal self-discipline, especially when wrongdoing becomes normalized.
No Vastu or temple-ritual rule is stated here; the verse functions as a moral diagnosis of Kali-yuga rather than a technical prescription.
