O my friends, sons of demons! In this material world, even those who are apparently advanced in education have the propensity to consider, “This is mine, and that is for others.” Thus they are always engaged in providing the necessities of life to their families in a limited conception of family life, just like uneducated cats and dogs. They are unable to take to spiritual knowledge; instead, they are bewildered and overcome by ignorance.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
विद्वानपीत्थं दनुजाः कुटुम्बं पुष्णन् स्वलोकाय न कल्पते वै । यः स्वीयपारक्यविभिन्नभाव- स्तमः प्रपद्येत यथा विमूढः
vidvānapītthaṃ danujāḥ kuṭumbaṃ puṣṇan svalokāya na kalpate vai | yaḥ svīyapārakyavibhinnabhāva- stamaḥ prapadyeta yathā vimūḍhaḥ
