Material enjoyment is indeed the cause of all unhappiness, but one cannot give it up unless one has personally experienced how much suffering it is. Therefore one should be allowed to remain in so-called material enjoyment while simultaneously advancing in knowledge to experience the misery of this false material happiness. Then, without help from others, one will find material enjoyment detestful. Those whose minds are changed by others do not become as renounced as those who have personal experience.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
नानुभूय न जानाति पुमान् विषयतीक्ष्णताम् । निर्विद्यते स्वयं तस्मान्न तथा भिन्नधीः परैः
nānubhūya na jānāti pumān viṣayatīkṣṇatām | nirvidyate svayaṃ tasmānna tathā bhinnadhīḥ paraiḥ
