About the becoming, existing and destruction of mankind. Each substance in universe begins to exist, exists a certain amount of time and disappears in the end. In between is the man. A social being, influenced by its surroundings and shaping its environment, trying to find the deeper meaning of existence. About the eternal dependence and the role of manipulation. Alone not strong enough and seeking strength in the mass. Beginning and end connected by what might lie in between. A constant exchange of matter. An unimportance which gained immense signification in the intensity of the moment.
