CHĀNDOGYA UPANISHAD · 6.11.2

अस्य यद् एकां शाखां जीवो जहात्य् अथ सा शुष्यति ।
द्वितीयां जहात्य् अथ सा शुष्यति ।
तृतीयां जहात्य् अथ सा शुष्यति ।
सर्वं जहाति सर्वः शुष्यति ॥

asya yad ekāṃ śākhāṃ jīvo jahāty atha sā śuṣyati ।
dvitīyāṃ jahāty atha sā śuṣyati ।
tṛtīyāṃ jahāty atha sā śuṣyati ।
sarvaṃ jahāti sarvaḥ śuṣyati ॥

'But if the life (the living Self) leaves one of its branches, that branch withers; if it leaves a second, that branch withers; if it leaves a third, that branch withers. If it leaves the whole tree, the whole tree withers.

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