KAṬHA UPANISHAD · 2.1.10

यदेवेह तदमुत्र यदमुत्र तदन्विह ।
मृत्योः स मृत्युमाप्नोति य इह नानेव पश्यति ॥ १०॥

yadeveha tadamutra yadamutra tadanviha ।
mṛtyoḥ sa mṛtyumāpnoti ya iha nāneva paśyati ॥ 10॥

What is in this world is also in the other, and what is in the other, that again is in this; who thinketh he sees difference here, from death to death he goeth.
