What will be the key to winning on the new stage of the twenty-first century? It is, first of all, winning over ourselves today, changing ourselves for the better today. Let’s deeply take this point to heart. Faith is the source of limitless strength. Religion is the earth from which culture flourishes. The Mystic Law is the wellspring of happiness. Our Buddhist practice gives us the strength to live, to grow, to win, and to surmount any kind of karma.

Daisaku Ikeda

If a plane flies off course or a car veers carelessly off the road, it can easily have an accident or fail to reach its destination. Similarly, if our lives go off course, we, too, can crash, plunging into misfortune and misery. Though it may not be visible to the eye, there is a path or course in life. A path leading to absolute happiness exists without a doubt—and that is the path of the Mystic Law.

Daisaku Ikeda

What is important is to have the feeling “That person is suffering, I want them to be happy” and also to talk about Buddhism with those around you from time to time. Even if the person you’ve been talking with doesn’t take faith right away, as long as you maintain a strong unwavering wish for their happiness and a sincere spirit of friendship, the time will definitely come when they will awaken to Buddhism.
