इमावेव गोतमभरद्वाजावयमेव गोत- मोऽयं भरद्वाज इमावेव विश्वामित्रजम- दग्नी अयमेव विश्वामित्रोऽयं जमदग्निरि- मावेव वसिष्ठकश्यपावयमेव वसिष्ठोऽयं कश्यपो वागेवात्रिर्वाचा ह्यन्नमद्यतेऽत्ति- र्ह वै नामैतद्यदत्रिरिति सर्वस्यात्ता भव- ति सर्वमस्यान्नं भवति य एवं वेद ॥ ४ ॥
In plain words
These two are Gotama and Bharadvāja — this one is Gotama, this one is Bharadvāja. These two are Viśvāmitra and Jamadagni — this one is Viśvāmitra, this one is Jamadagni. These two are Vasiṣṭha and Kaśyapa — this one is Vasiṣṭha, this one is Kaśyapa. And Speech alone is Atri, because it's speech that eats the food. 'Eating' — that's the secret folded into the name, which is why he's called Atri. Whoever knows this becomes the eater of everything; everything in the world becomes his food.
