For there is one Rudra only, they do not allow a second, who rules all the worlds by his powers. He stands behind all persons, and after having created all worlds he, the protector, rolls it up at the end of time.

In plain words: There is only one Rudra, a name for God here, with no second. He rules all the worlds by his powers and stands behind every person. He creates and protects the worlds, and at the end of time he gathers them back into himself.
