Sutta Reference of Buddhism Not being a Philosophy

I am looking for the proper Suttra/Dhammapada in which the Buddha states the following. > My teaching is not a philosophy. It is the result of direct > experience... My teaching is a means of practice, not something to > hold onto or worship. My teaching is like a raft used to cross the > river. Only a fool would carry the raft around after he had already > reached the other shore of liberation.
