Buddhism is strict. Our commitment in faith must be firm and true. Self-centeredness and arrogance not only destroy one’s own faith but also that of others. Arrogance is a devilish function that destroys faith. Only by banishing arrogance can we achieve new growth and development in kosen-rufu. Please deeply engrave this in your hearts.
