THE SECOND CATEGORY are ordinary servants. They do not know why they are working or that they are being employed by the glorious lord. He causes them to work through his own ideas and knowledge and gives them an appropriately small wage. These servants are unaware of what various and comprehensive aims and exalted matters result as a consequence of their work. Some of them even imagine that their work concerns themselves alone and has no aim besides their wage.

THE THIRD CATEGORY: The lord of all dominion has some animals which he employs in various jobs in the construction of the city and palace. He only gives them fodder, but their working at tasks suitable for their abilities gives them pleasure. For, if a potentiality or ability is realized in action and work, there is a breathing in and expansion and this results in pleasure. The pleasure to be had from all activity stems from this. The wage and remuneration of this sort of servant, then, is only fodder and that pleasure.

THE FOURTH CATEGORY are workers who know what they are doing, and why and for whom they are working, and why the other workers are working, and what the purpose of the lord of all dominion is, and why he is causing them to work. Workers of this category are therefore bosses and supervisors over the other workers. They receive remuneration that is graded according to their rank and degree.

In exactly the same way, the Sustainer of All the Worlds, Who is the All-Glorious Lord of the heavens and the earth and the All-Beauteous Builder of this world and the hereafter, employs both angels, and animals, and inanimate beings and plants, and human beings in the palace of this world, in this realm of causality. He employs them not out of need, for the Creator of everything is He, but for certain instances of wisdom, like the functioning of His might, sublimity, and dominicality. He causes them to worship and has charged these four categories with different duties of worship.

The First Category is the angels, who are represented in the comparison by the slaves. For the angels there is no endeavour and progress; they all have their fixed station and determined rank, and receive a particular pleasure from the work itself and an emanation from their worship. That is to say, the reward of these servants is found within their duties. Just as man is nourished by air, water, light, and food, and receives pleasure from them, so are the angels nourished by the varieties of remembrance, glorification, praise, worship, knowledge, and love of God, and take pleasure in them. For, since they are created out of light, light is sufficient for their sustenance. Fragrant scents, even, which are close to light, are a sort of nourishment for them which they enjoy. Indeed, good spirits take pleasure in sweet smells.
