Ego-generated emotions are derived from the mind's identification with external factors which are, of course, all unstable and liable to change at any moment. The deeper emotions are not really emotions at all but states of Being. Emotions exist within the realm of opposites. States of Being can be obscured, but they have no opposite. They emanate from within you as the love, joy, and peace that are aspects of your true nature.
— Eckhart Tolle
