Happiness

What is happiness and why is it important?
What is the definition of happiness? What are the different types of happiness? What are the factors that make it important?
Different philosophers have different definitions of happiness. For example, Aristotle defines happiness and live the good life. That is true, I would say that the necessary foundation for happiness, but I would define happiness as a feeling of pleasure and harmony in the emotional, based on a perception that it is a safe and loved, as I distinguish it from pleasure is just a good feeling in the senses, or the joy more spiritual is a rarefied kind of good feeling (by the way, can coexist with suffering in the physical or even emotional level) ..
