Cultivation and Worldly Activities
For farmers the growing of crops is kufu; for carpenters and plasterers the construction of buildings is kufu. Drawing on this secular meaning, the word came to indicate cultivation of the Buddhadharma for seekers of the Way.
Some people have a formal practice, attend many retreats, and feel like, Yes!, they are on the Way. Others have no teacher or group to associate with and meditate each day at a certain time.
