CHĀNDOGYA UPANISHAD · 2.24.6

अत्र यजमानः परस्ताद् आयुषः स्वाहा ।
अपजहि परिघम् इत्य् उक्त्वोत्तिष्ठति ।
तस्मै वसवः प्रातःसवनं संप्रयच्छन्ति ॥

atra yajamānaḥ parastād āyuṣaḥ svāhā ।
apajahi parigham ity uktvottiṣṭhati ।
tasmai vasavaḥ prātaḥsavanaṃ saṃprayacchanti ॥

'I (the sacrificer) shall go thither, when this life is over. Take this! (he says, in offering the libation.) Cast back the bolt!' Having said this, he rises. For him the Vasus fulfil the morning-oblation.
