KAṬHA UPANISHAD · 2.3.4

इह चेदशकद्बोद्धुं प्राक्शरीरस्य विस्रसः ।
ततः सर्गेषु लोकेषु शरीरत्वाय कल्पते ॥ ४॥

iha cedaśakadboddhuṃ prākśarīrasya visrasaḥ ।
tataḥ sargeṣu lokeṣu śarīratvāya kalpate ॥ 4॥

If in this world of men and before thy body fall from thee, thou art able to apprehend it, then thou availest for embodiment in the worlds that are His creations.
