From one perspective, Buddhist practice means plunging into the midst of the people and striving to strengthen our life force to the greatest extent. The purpose of SGI activities is for each of us to be able to build a strong, invincible, diamondlike self that can overcome every difficulty and blaze a way forward wherever we go. Obstacles are a golden opportunity to quickly forge an inner self that is as indestructible as a diamond, able to endure for eternity.
