法華玄論 10.81

10.81

答：如前說。長為短用、短為長用，長短為非長短用、非長短為長短用。此是如來究竟自在無礙之身，即有究竟自在無方之大用。始行之人分得此悟，故六根自在也。

Answer: As said before: the long functions as the short, the short functions as the long; the long and short function as neither long nor short, and neither long nor short functions as long and short. This is the Tathāgata's ultimate, unconstrained, unobstructed body, which immediately possesses the ultimate, unconstrained, and directionless great function. Persons of initial practice attain a fraction of this awakening, and therefore their six sense faculties are unconstrained.
