As we have seen, if we studied human nature more keenly we would find a great many examples of people with an angelic nature, and also of those who show jinn qualities; however, there are more people who show human qualities. These can again be divided into three classes: there is the human quality, there is the animal quality, and there is the devilish quality, depending on the rate of vibrations and the rhythm. Intense rhythm produces the devilish quality; moderate rhythm shows the animal quality; an even rhythm shows the human quality. The form of this rhythm may be described thus: that the human quality is mobile, the animal quality is uneven, and the devilish quality is zigzag.
