" The Great Course is unproclaimed. Great demonstration uses no words. (2:34) Great Humanity is not humane. Great rectitude is not fastidious. Great courage is not invasive. For when the Course becomes explicit, it ceases to be the Course. When words demonstrate by debate, they fail to communicate. When Humanity is constantly sustained, it cannot reach its maturity.21 When rectitude is pure, it cannot extend itself to others. When courage is invasive, it cannot succeed.22 These five are originally round, but they are forced toward squareness. "
