As is explained in the Fourth Branch of the Twenty-Fourth Word, the first of the four categories of workers employed by the All-Glorious Maker of the palace of this world is that of the angels and spirit beings. Since, without knowing it, plants and inanimate beings perform extremely important though wageless duties at the command of One Who does know; also without knowing it, animals serve extensive universal aims in return for an insignificant wage; and since, observedly, in return for two wages, one immediate and the other postponed, human beings, knowing the All-Glorious Maker’s aims, are employed through their conforming to them, their taking a share of everything for themselves, and their supervising the other servants; it will certainly be the first category, as well as the fourth, which will constitute the servants and workers. They both resemble human beings in that knowing the universal aims of the All-Glorious Maker, they conform to them through worship, and they are contrary to them. For being beyond sensual pleasure and some partial wage, they consider sufficient the pleasure, perfection, delight and bliss they experience through the All-Glorious Maker’s attention, command, favour, consideration, and name, through their perception of Him, connection with Him, and proximity to Him. They labour with the purest sincerity, their duties of worship varying according to their different kinds, and according to the varieties of the creatures in the universe.
