Explanation:

The main aim of God entering into the world is to give excellent guidance to the spiritual aspirants. No soul can give such exceptional guidance equal to God. Such guidance is based on the exceptional unique knowledge of omniscient God. Since He is the author of the spiritual scriptures, He alone can give the correct interpretation and the essence of all the scriptures. Since the same God came in different forms to different parts of the world and gave the exceptional spiritual guidance to the entire humanity through the scriptures of various religions, He alone can correlate all the scriptures and establish the Universal Spirituality and the subsequent peace and harmony in the world. Such basic exceptional and universal spiritual knowledge is called as Prajnanam. For this purpose, it goes without saying that the suitable medium to fulfill this main aim is only the human body. Hence, God comes in human form only to accomplish this excellent goal.
