Shoju practice is using last year's calender

"There is doubt that we should not read the provisional teaching because of my sentence in the 'True Object of Worship'. This is a wrong view. As a result, I sometimes wrote that you must discard the provisional gate. The provisional gate [I referred to] is not the provisional teaching [of the Hoben chapter] we now read. I refuted the provisional teaching of the Mt. Hiei Tendai sect as a teaching whose time is past. If you practice* according to T'ien-t'ai and Dengyo in the Latter Day of the Law, it is like using last year's calendar." (Gosho Zenshu, p. 972)

*Practice shoju instead of shakubuku
