Next come the other Stotras with which the priest may obtain food for himself by singing them. Therefore let the sacrificer, while these Stotras are being sung, ask for a boon, whatever desire he may desire. An Udgatri priest who knows this obtains by his singing whatever desire he may desire either for himself or for the sacrificer. This (knowledge) indeed is called the conqueror of the worlds. He who thus knows this Saman, for him there is no fear of his not being admitted to the worlds.

In plain words: During the other chants, the worshipper may ask for any wish he has. A priest who understands this chant can win, by his singing, whatever is wished for himself or for the worshipper. This knowledge is called the conqueror of worlds. Whoever has it need not fear being shut out of any world.
