Due to ignorance, the materialistic person does not know anything about his real self-interest, the auspicious path in life. He is simply bound to material enjoyment by lusty desires, and all his plans are made for this purpose. For temporary sense gratification, such a person creates a society of envy, and due to this mentality, he plunges into the ocean of suffering. Such a foolish person does not even know about this.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
लोकः स्वयं श्रेयसि नष्टदृष्टि- र्योऽर्थान् समीहेत निकामकामः । अन्योन्यवैरः सुखलेशहेतो- रनन्तदुःखं च न वेद मूढः
lokaḥ svayaṃ śreyasi naṣṭadṛṣṭi- ryo'rthān samīheta nikāmakāmaḥ | anyonyavairaḥ sukhaleśaheto- ranantaduḥkhaṃ ca na veda mūḍhaḥ
