Translation: - About God, normally it is said that He is formless i.e. who never takes birth. Others say that He is in form i.e. takes birth in the form of an incarnation. Those who are (dheeranam) completely knowledgeable narrate properly whether that God takes birth or not. They impart proper i.e. accurate first-hand knowledge on this topic in different ways. Listen to the correct knowledge about God from those knowledgeable mahatmas.
