“ Life finds its purpose and fulfillment in the expansion of happiness. ”
The constitution of the universe is total natural law. 'Natural law,' we say from the field of science. 'Will of God,' we say from the field of religion. It's the same thing.
~ Maharishi Mahesh Yogi
Happiness radiates like the fragrance from a flower and draws all good things towards you.
Problems or successes, they all are the results of our own actions. Karma. The philosophy of action is that no one else is the giver of peace or happiness. One's own karma, one's own actions are responsible to come to bring either happiness or success or whatever.
Being happy is of the utmost importance. Success in anything is through happiness.
