Bhagwad Gita
Chapter 1, Verse 41
अधर्माभिभवात्कृष्ण प्रदुष्यन्ति कुलस्त्रियः।
स्त्रीषु दुष्टासु वार्ष्णेय जायते वर्णसङ्करः।।1.41।।
When there is an increase of unwanted population, a bad situation arises for both the family and those who disrupt family traditions. In such fallen families, people stop honoring their ancestors through rituals like offering food and water.
