Happiness is a measure of the overall health, growth, and harmony of the entire body and mind.
Happiness also reflects our perception of the harmony and functioning of the external world.
The biological happiness mechanism has safeguards against lack of concern about other people and lack of concern about the future. To make happiness our ultimate concern in life is to align our conscious ultimate concern with the most basic human motives and universal forces. If we all seek happiness for self and others, humankind can evolve into a highly integrated organism that will maximize the happiness for all.
