Verse 4.13.2

स य एतमेवं विद्वानुपास्तेऽपहते पापकृत्यां लोकी भवति सर्वमयुरेति ज्योग्जीवति नास्यावरपुरुषाः क्षीयन्त उप वयं तं भुञ्जामोऽस्मिंश्च लोकेऽमुष्मिंश्च य एतमेवं विद्वानुपास्ते ॥ ४.१३.२ ॥
॥ इति त्रयोदशः खण्डः ॥

|| iti trayodaśaḥ khaṇḍaḥ ||

2. ‘He who knows this Āhavanīya fire and worships it thus has all his sins removed, and he attains the world of the Āhavanīya fire. He lives a long and bright life, and his descendants do not perish. In this world and the next, we look after that person who knows this fire and worships it thus’.

Word-for-word explanation:

Saḥ yaḥ, he who; etam evam vidvān, knowing this in this way; upāste, [and] worships; apahate pāpa- kṛtyām, he destroys his sins; lokī bhavati, becomes a dweller in the world of the god of fire; sārvam āyuḥ eti, lives the full range of his life; jyok jīvati, he lives a bright life; asya āvarapuruṣāḥ, his descendants; na kṣīyante, do not perish [i.e., his line is never broken]; asmin ca loke amuṣmin ca, in this world and also in the other world; vayam tam upabhuñjāmaḥ, we will look after him; yaḥ etam evam vidvān upāste, he who knows this [fire] thus and worships it. Iti trayodaśaḥ khaṇḍaḥ, here ends the thirteenth section.
