There is no point in defining God when you do not understand God. God is not definable. We are always used to thinking in terms of finding and seeing things our way because we are ignorant and impure. Hindus have defined God by saying that any you can conceive, imagine, think or argue is not God. God is beyond all. He is beyond this universe, therefore, he is beyond your physical or intellectual imagination. 

--Swami Radhanandaji
