Each person comes into this world with a specific destiny--he has something to fulfill, some message has to be delivered, some work has to be completed. You are not here accidentally--you are here meaningfully. There is a purpose behind you. The whole intends to do something through you.
I believe that the very purpose of our life is to seek happiness. That is clear. Whether one believes in religion or not, whether one believes in this religion or that religion, we all are seeking something better in life. So, I think, the very motion of our life is towards happiness.
I do not trust people who don't love themselves and yet tell me, 'I love you.' There is an African saying which is: Be careful when a naked person offers you a shirt.
