The ancients sometimes said that the worst sin is ingratitude, which is a forgetting of the greatness, beauty, truth, and goodness of the Source that is constantly creating us-- in other terms, a forsaking of Being and of the Good.
Every great activity and event, every true encounter with the Divine must begin by our turning off the mind and turning within to that place where true wisdom resides. Ideas are born in the quiet of the mind. Nature gives us the model for our spiritual endeavors, teaching us to silence outer confusion and noise so Spirit's soft voice can be heard. We encounter the Divine in the stillness at the center of our being.
