ChU 2.21.4
यस् तद् वेद स वेद सर्वम् । सर्वा दिशो बलिम् अस्मै हरन्ति । सर्वम् अस्मीत्य् उपासित । तद् व्रतं तद् व्रतम्
yas tad veda sa veda sarvam | sarvā diśo balim asmai haranti | sarvam asmīty upāsita | tad vrataṃ tad vratam
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He who knows this, knows everything. All regions offer him gifts. His rule is, 'Let him meditate (on the Sâman), knowing that he is everything, yea, that he is everything.'
Translated by F. Max Müller
