You will say: "Then, if we inherit the attributes of our father, our mother, acquire the attributes of the jinns and angels, how can we help how our character is?" A man may say: "I am an angry person, because my father was an angry person." "I am a moody person, because my grandfather was a moody person." "I cannot help this, it is my character." This is half true, but it is developed by belief. The soul acquires only those qualities in which it is interested. If the soul is not interested in the qualities, it will never take them. And the soul keeps only those attributes in which it is interested. If it is not interested in them, it loses them. However wicked a person may be, however many undesirable attributes he may have, he can lose them all if he does not approve of them.
