jyog jīvati \
na asya avarapuruṣāḥ kṣīyante \
upa vayaṃ taṃ bhuñjāmo 'smiṃś ca loke amuṣmiṃś ca \
ya etam evaṃ vidvān upāste \\411.2\

‘He who knows it thus and meditates on it, destroys sinful acts, wins the region (of fire), reaches the full length of life, lives gloriously, and his descendants never perish. We protect him in this world and in the next who knows it thus and meditates on it.’
