"When there is gratitude, complaints disappear... When there is complaint in the mind, there is discontent, frustration and depression - all that follows. If you are not grateful... you will find fault. Even if there is none, you will try to see it. Your mind will find it for you.
This is the lower journey. Gratitude is the middle way. And as you rise above that... gratitude flows out from you as grace."
