The heart becomes wide by forgetting self, but narrow by thinking of the self and pitying one's self. To gain a wide and broad heart you must have something before you to look upon, and to rest your intelligence upon - and that something is the God-ideal.
Hazrat Inayat KhanThe more sincerity is developed, the greater share of truth you will have. And however much sincerity a person may have, there is always a gap to fill, for we live in the midst of falsehood, and we are always apt to be carried away by this world of falsehood. Therefore we must never think we are sincere enough, and we must always be on our guard against influences which may carry us away from that sincerity which is the bridge between ourselves and our ideal. No study, no meditation is more helpful than sincerity itself.
