CHĀNDOGYA UPANISHAD · 8.3.1

त इमे सत्याः कामा अनृतापिधानाः ।
तेषां सत्यानां सताम् अनृतम् अपिधानम् ।
यो यो ह्य् अस्येतः प्रैति न तम् इह दर्शनाय लभते ॥

ta ime satyāḥ kāmā anṛtāpidhānāḥ ।
teṣāṃ satyānāṃ satām anṛtam apidhānam ।
yo yo hy asyetaḥ praiti na tam iha darśanāya labhate ॥

'These true desires, however, are hidden by what is false; though the desires be true, they have a covering which is false. Thus, whoever belonging to us has departed this life, him we cannot gain back, so that we should see him with our eyes.

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