It is this spiritual freedom — which cannot be taken away — that makes life meaningful and purposeful. An active life serves the purpose of giving man the opportunity to realize values in creative work, while a passive life of enjoyment affords him the opportunity to obtain fulfillment in experiencing beauty, art, or nature. But there is also purpose in that life which is almost barren of both creation and enjoyment and which admits of but one possibility of high moral behavior: namely, in man’s attitude to his existence, an existence restricted by external forces.  – Viktor Frankl (Source: Brainpickings)
