Ramakrishna quotes - page 7
A thief enters a dark room and feels the various articles therein. He lays his hands upon a table perhaps, and saying "Not this" passes on. Next he come upon some other article - a chair, perhaps - and again saying "Not this" continues his search, till, leaving article after article, he finally lays his hands on the box containing the treasure. Then he exclaims "It is here!"
Ramakrishna
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.
Ramakrishna
