अग्निर्हिंकारो वायुः प्रस्ताव आदित्य उद्गीथो नक्षत्राणि प्रतिहारश्चन्द्रमा निधनमेतद्राजनं देवतासु प्रोतम् ॥ २.२०.१ ॥
In plain words
Fire is the hiṃkāra, the wind the prastāva, the sun the udgītha, the constellations the pratihāra, the moon the nidhana. This is the Rājana chant woven upon the deities.
The commentators
Chāndogyopaniṣadbhāṣyam· bhāṣya
अग्नि हिंकार , प्रथमस्थानत्वात् । वायु प्रस्ताव , आन- न्तर्यसामान्यात् । आदित्य उद्गीथ , श्रेष्ठ्यात् । नक्षत्राणि प्रतिहार , प्रतिहृतत्वात् । चन्द्रमा निधनम् , कर्मिणा तन्निध- नात् । एतद्राजन देवतासु प्रोतम् , देवताना दीप्तिमत्त्वात् ॥
In plain words
Whoever knows this rāja sāman to be thus strung across the deities attains shared worlds, shared majesty, and intimate union with those very powers. He lives out his full span of life, thrives long, and grows great in offspring, cattle, and renown. Let him never speak ill of brāhmaṇas—that is his sacred vow.
Close to the Sanskrit
He who thus knows this rāja woven in the deities attains the very same world, the same opulence, and intimate union with those very deities; he attains the full lifespan, lives long, becomes great by progeny and cattle, and great by fame. He should not disparage brāhmaṇas; that is his vow.
