Through polluted intelligence one is subjected to the modes of nature, and thus one is conditioned by material existence. Like a dreaming state in which one falsely suffers, material existence, which is due to ignorance, must be considered unwanted and temporary.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
एतद्द्वारो हि संसारो गुणकर्मनिबन्धनः । अज्ञानमूलोऽपार्थोऽपि पुंसः स्वप्न इवेष्यते
etaddvāro hi saṃsāro guṇakarmanibandhanaḥ | ajñānamūlo'pārtho'pi puṃsaḥ svapna iveṣyate
