The key is to become happy right here and now, in your present situation and circumstances, just as you are. My young friends, be pioneers of life! Be great victors of happiness! Don’t lose yourself in idle, empty, mundane pleasures and amusements! Take your place at the head of the march to fundamental happiness!

Daisaku Ikeda

Wherever practitioners of the Lotus Sutra chant Nam-myoho-renge-kyo, just as an echo answers a sound and a shadow follows a form, their prayers will unfailingly produce positive results there. The Daishonin teaches that our lives are transformed—both spiritually and physically—by prayer, which in turn exerts a positive influence on our environment.

Daisaku Ikeda

In the course of this long journey, it is only natural that we should meet with obstacles and difficulties from time to time. If we have hardships to overcome, we can grow and savor exhilarating joy once we surmount them. And when we strive with courageous, pure-hearted faith, all difficulties are transformed into a source of benefit and good fortune, becoming springboards for creating an even brighter future.
