Freedom through expression. Expression simply means that you are more natural. Being natural is happiness and fulfilment itself, no matter what you do in your daily life, it does not depend on profession or relationships.
Society usually creates an image, which you believe you should fulfill in order to function in it. But it also creates a repression. Repressed energy manifests through stagnancy, addictions, obsessions, aggression and other destructive emotions and behaviors, which is painful for society and individual.
There is no growth, no freedom in suppression. To be free means to be free from conditioning, rules and beliefs outside you.
