If you feel proud, let it be in the thought that you are the servant of God, the son of God. Great men have the nature of a child. They are always a child before Him; so they are free from pride. All their strength is of God and not their own. It belongs to Him and comes from Him.
Who may be called a paramahamsa? He who, like a swan, can take the milk from a mixture of milk and water, leaving aside the water. He who, like an ant, can take the sugar from a mixture of sugar and sand, leaving aside the sand.
It's enough to have faith in one aspect of God. You have faith in God without form. That is very good. But never get into your head that your faith alone is true and every other is false. Know for certain that God without form is real and that God with form is also real. Then hold fast to whichever faith appeals to you.
What Brahman is cannot be described. All things in the world — the Vedas, the Puranas, the Tantras, the six systems of philosophy — have been defiled, like food that has been touched by the tongue, for they have been read or uttered by the tongue. Only one thing has not been defiled in this way, and that is Brahman. No one has ever been able to say what Brahman is.
