The flames of fire are of two types. With one type of flame everything becomes ashes, while the other type of flame gives life to everything. When the son of Adam develops himself with the light of goodness, then these bursting flames become a garden of flowers. But when the son of Adam develops himself with the leaven of evil, then these bursting flames push him into the fires of hell. What are good and evil? They are two ways of naming ways of thinking. If the way of thinking has devotion and love of God, then it is good. But if the way of thinking has the love of anyone except God, then it is evil. Good is grounded in God and evil is rooted in evil. The definition of Good is that God likes it, and, on the other hand, evil is something that God does not like.
