Life is like a book with three chapters. Two are already written by God - Birth and Death. The chapter in the middle is empty; fill it with your smile, love and faith.
If you seek to understand the whole universe you will understand nothing at all but seek to understand yourself and you will understand the whole universe.
All ups and downs help you to find a balance in your being. No more ups and downs, but bliss, joy, silence and gratitude.
