Thank you very much! It is great definition.

"Realize that true happiness lies within you. Waste no time and effort searching for peace and contentment and joy in the world outside. Remember that there is no happiness in having or in getting, but only in giving. Reach out. Share. Smile. Hug. Happiness is a perfume you cannot pour on others without getting a few drops on yourself." This definition of happiness by Og Mandino

there is no precise definition of happiness. it depends on one's own feeling

happiness is joy, bliss, contentment...

probably it is free))
