From him come the Rik, the Sâman, the Yagush, the Dîkshâ (initiatory rites), all sacrifices and offerings of animals, and the fees bestowed on priests, the year too, the sacrificer, and the worlds, in which the moon shines brightly and the sun.

In plain words: Everything to do with worship comes from the one Person, the source of all. This includes the sacred hymns of the Vedas (the Rik, Saman and Yajus), the rites that start a person's religious life, all sacrifices, and the gifts paid to priests. The year, the worshipper, and the worlds lit by the sun and moon come from him too.
