MUṆḌAKA UPANISHAD · 1.2.9

अविद्यायां बहुधा वर्तमाना वयं
कृतार्था इत्यभिमन्यन्ति बालाः ।
यत्कर्मिणो न प्रवेदयन्ति रागात्तेनातुराः क्षीणलोकाश्च्यवन्ते ॥ ९॥

avidyāyāṃ bahudhā vartamānā vayaṃ
kṛtārthā ityabhimanyanti bālāḥ ।
yatkarmiṇo na pravedayanti rāgāttenāturāḥ kṣīṇalokāścyavante ॥ 9॥

They dwell in many bonds of the Ignorance, children thinking, “We have achieved our aim of Paradise”; for when the men of works are held by their affections, and arrive not at the Knowledge, then they are overtaken by anguish, then their Paradise wastes by enjoying and they fall from their heavens.

Sri Aurobindo · CWSA 18, pp. 134, 135
