Why does happiness slip through our fingers, even when we achieve it? Inherent in us is a basic aspiration for happiness, yet the definition of happiness changes as we develop. In order to achieve true happiness, one must first acquire a lack of happiness. A person who has a deficiency that is constantly increasing and discovers how to fulfill it each time achieves eternal happiness. Today, we are facing a new stage in our human development in which we must develop ourselves towards internal, emotional fulfillment.
