KAṬHA UPANISHAD · 1.1.23

शतायुषः पुत्रपौत्रान्वृणीष्वा
बहून्पशून् हस्तिहिरण्यमश्वान् ।
भूमेर्महदायतनं वृणीष्व
स्वयं च जीव शरदो यावदिच्छसि ॥ २३॥

śatāyuṣaḥ putrapautrānvṛṇīṣvā
bahūnpaśūn hastihiraṇyamaśvān ।
bhūmermahadāyatanaṃ vṛṇīṣva
svayaṃ ca jīva śarado yāvadicchasi ॥ 23॥

“Choose sons and grandsons who shall live each a hundred years, choose much cattle and elephants and gold and horses; choose a mighty reach of earth and thyself live for as many years as thou listest.
