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.'

In plain words: An old verse is quoted to support this. It says the three groups (the Vedas, the worlds and so on), each arranged in the five parts of the chant, along with the other forms of the chant, are the highest thing, and nothing is greater.
