ChU 2.21.3
तद् एष श्लोकः । यानि पञ्चधा त्रीणि त्रीणि । तेभ्यो न ज्यायः परम् अन्यद् अस्ति
tad eṣa ślokaḥ | yāni pañcadhā trīṇi trīṇi | tebhyo na jyāyaḥ param anyad asti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
And thus it is said in the following verse: 'There are the fivefold three (the three kinds of sacrificial knowledge, the three worlds &c. in their fivefold form, i.e. as identified with the hinkâra, the prastâva, &c), and the other forms of the Sâman. Greater than these there is nothing else besides.'
