Avicenna on happiness and it's relation with knowledge and worship

Avicenna believes thatthetrue happiness andadversity come into being in the other world, but the knowledge and worship in this world are remedy of that happiness, and ignorance and rebellion are its poison. In other word, absolute happiness is available through perfection and purification. The perfection through knowledge and purification through action and also worship are obtained.Worship is a way toward knowing of transcendental God because it is the worship that transforms rational soul into pure intellect and until it is not to be pseudo- angel; it will not be way of knowing of transcendental God. Knowledge of God and pure intellects fascinate man to connect to the pure intellects and become resembleof them. Surely, true desire causes to weep and constant recite as well as true worship in man. In fact, knowledge and worship have double relation each other: true worship leads to true knowledge and knowledge itself is a sublime worship which it presents that God is infinity being. This way can continue to ad infinum. And thus man can obtain true worship.
