法華義疏 3.51

3.51

凡有四句：一者、於昔為實、於今為權，謂對今一以望昔三是也。二者、今昔俱實，昔以三為實，今以一為實。三者、三一俱權，望正道為論，未曾三一，三一皆為開道名為道門，故皆權也。四者、今實昔權，今以一為實，於昔為非實義名為權。

There are four propositions overall: First, real in the past and provisional in the present: this refers to viewing the past three in contrast to the present one. Second, both past and present are real: the past takes the three as real, and the present takes the one as real. Third, both three and one are provisional: discussed in view of the correct path, there has never been three or one; both three and one are opening the path and are called gateways to the path, so both are provisional. Fourth, real in the present and provisional in the past: the present takes the one as real, and in relation to the past it is non-real in meaning, termed provisional.
