I am so glad to learn that you are interested in the matter of Vaisnava philosophy. Vaisnava philosophy is very simple: that God is great and everyone is His servant. Nobody can be equal to or greater than God. They are simultaneously one and different. In quality they are one, but in magnitude they are different. This is the whole philosophy of the four Vaisnava sampradayas.
