If a person is adopting wrong ways, a true friend should not be afraid of pointing out his errors with a view to improving him.  You should make a determination to cultivate friendships only based upon Prema (Love).  Only such sacred friendships associated with Prema, springing from the fountain of one's heart, is true friendship.  It is not enough to merely share joy with each other; it is more important to share sorrow with each other.  True friendship is that, which enables one to help others, at all times, and in all circumstances.  You must transcend dissension and live in harmony, by raising your hearts to God.

-Divine Discourse, Summer Showers, 1973.

"You must make God your True Friend." - Baba
