The true great benefit of faith is this fundamental inner transformation and human revolution. According to the principle of the oneness of life and its environment, when our life state changes, we are able to change our environment as well and thereby resolve all of our problems.

Daisaku Ikeda

The lives of Soka Gakkai members, who pray wholeheartedly for the happiness of their friends and earnestly share the Daishonin’s teachings with others, brim with joy, courage, and hope. Though we may be struggling with various health, financial, or other problems, we can overcome them confidently, like an accomplished surfer who enjoys riding big waves.

Daisaku Ikeda

The obstacles in question are the three obstacles and four devils. We cannot attain enlightenment without struggling against them. We cannot become Buddhas without experiencing and overcoming difficulties—just as we cannot graduate from university without taking examinations and passing them.
