That is the main goal of his life to be happy all the time. All his energy of thoughts, feelings and emotions are flowing to be happy. He understands very well what it takes to go through sadness for long period of time. He started experiencing the God within himself and became very successful afterwards. I mean really very very successful. And then he started realising, something is missing. Despite being successful and can have almost anything he wants and still he is unhappy. So he started exploring the mechanism of happiness. With God’s help he figured out what commands his thoughts, feelings and emotions and inspires his hopes. And remained happy no matter what the circumstances are.
