SGI President Ikeda’s Daily Encouragement:
Compassion is the very soul of Buddhism. To pray for others, making their problems and anguish our own; to embrace those who are suffering, becoming their greatest ally; to continue giving them our support and encouragement until they become truly happy—it is in such humanistic actions that the Daishonin’s Buddhism lives and breathes.
