Harmony

It's all about the relations. Don't believe me? Friend, just look at the music, relationships, economy, chemistry...
Alone is nothing in this world, loneliness is the fictional diarrhea of self-absorbed people. Every action carries significant consequence. And that is the bane of excessive egoism. Our mind tends to wander only in his own playground, never able to expand beyond its backyard.
What would be evil without good and beauty without the ugliness. Humans can only comprehend extremes, because there is relationship of contrast between them.
The moment every part of the work touch itself, that is the harmony among the anything you can imagine. The music of spheres as would the Pythagoreans said.
