CHĀNDOGYA UPANISHAD · 5.9.2

स जातो यावदायुषं जीवति ।
तं प्रेतं दिष्टम् इतो ऽग्नय एव हरन्ति यत एवेतो यतः संभूतो भवति ॥

sa jāto yāvadāyuṣaṃ jīvati ।
taṃ pretaṃ diṣṭam ito ’gnaya eva haranti yata eveto yataḥ saṃbhūto bhavati ॥

'When born, he lives whatever the length of his life may be. When he has departed, his friends carry him, as appointed, to the fire (of the funeral pile) from whence he came, from whence he sprang.

F. Max Müller · The Upanishads, Sacred Books of the East 1 (1879)
