KAṬHA UPANISHAD · 1.1.12

स्वर्गे लोके न भयं किंचनास्ति
न तत्र त्वं न जरया बिभेति ।
उभे तीर्त्वाऽशनायापिपासे
शोकातिगो मोदते स्वर्गलोके ॥ १२॥

svarge loke na bhayaṃ kiṃcanāsti
na tatra tvaṃ na jarayā bibheti ।
ubhe tīrtvā’śanāyāpipāse
śokātigo modate svargaloke ॥ 12॥

“In heaven fear is not at all, in heaven, O Death, thou art not, nor old age and its terrors; crossing over hunger and thirst as over two rivers, leaving sorrow behind the soul in heaven rejoices.
