And through causing the motion of minerals and employing them, He confers on them the rank of the degree of vegetable life. And by presenting vegetable life in the form of sustenance, He grants it, through its motion and employment, the degree of fineness of animal life. And through employing the particles in animals, He raises them by way of being sustenance to the degree of human life. And by purifying the particles in a human body through repeated filtering, and by favouring them, He promotes them to the most delicate and subtle places, which are the brain and the heart. From all this it may be understood that the motion of particles is not without wisdom, but that the particles are made to hasten to a sort of perfection worthy of themselves.

Thirdly: Among the particles in animate beings, some, like those in pips and seeds, receive such a light, fineness, and quality that they are like a spirit or a king to the rest of the particles, to a huge tree, for example. Thus, since among all the particles of a huge tree some rise to this rank through fulfilling their delicate duties and passing through the many stages in the life of the tree, it demonstrates that through the command of the All-Wise Maker these particles receive a fineness, light, rank, and instruction on account of and in honour of the Divine Names manifested on them in accordance with the sorts of motion that are the functions of their natures, and in honour of them.
