असन्तुष्टस्य विप्रस्य तेजो विद्या तपो यश: ।
स्रवन्तीन्द्रियलौल्येन ज्ञानं चैवावकीर्यते ॥
asantuṣṭasya viprasya tejo vidyā tapo yaśaḥ |
sravantīndriya-laulyena jñānaṁ caivāvakīryate ||
(Śrīmad Bhāgavatam: 7.15.19)
“On account of greed related to the senses, an unsatisfied brāhmaṇa’s potency, learning, austerity, and fame dwindle, and his awareness [i.e., discernment] too is certainly cast away.”
