Ka means “house” or “home,” and jo means “usual” or “everyday.” So kajo means “everyday” or “everyday life.” People are often prone to think that religious matters should be different from daily life, being more sacred than and superior to daily life. But according to Buddhist theory, Buddhist life is nothing other than our daily life. Without daily life there can never be Buddhism. In China it was said that wearing clothes and eating meals are just Buddhism. In this chapter, Master Dogen explains the meaning of kajo, everyday life, on the basis of Buddhism.
