KAṬHA UPANISHAD · 1.2.6

न साम्परायः प्रतिभाति बालं
प्रमाद्यन्तं वित्तमोहेन मूढम् ।
अयं लोको नास्ति पर इति मानी
पुनः पुनर्वशमापद्यते मे ॥ ६॥

na sāmparāyaḥ pratibhāti bālaṃ
pramādyantaṃ vittamohena mūḍham ।
ayaṃ loko nāsti para iti mānī
punaḥ punarvaśamāpadyate me ॥ 6॥

The childish wit bewildered and drunken with the illusion of riches cannot open its eyes to see the passage to heaven; for he that thinks this world is and there is no other, comes again and again into Death’s thraldom.
