A high degree of evolution.

Man and woman are the leading civilization forward. They can not exist alone, but need to develop a spirit of coordination, mutual love and respect. It is as if the woman was pushing the world with his love. Love is what prevents us from seeing the life of dry form, gives us hope and devote their energies to higher causes. The man, with his power, pull with a car the world up. It is the power to do things, to create and build worlds. But without love, power becomes overbearing; If the power fail, love becomes illusion. When both are together, moving in a coordinated fashion, civilization reaches a high degree of evolution.
