首楞嚴義疏注經 4.480

4.480

「十方如來於十八界一一修行，皆得圓滿無上菩提，於其中間亦無優劣。但汝下劣，未能於中圓自在慧，故我宣揚，令汝但於一門深入，入一無妄，彼六知根一時清淨。」

"The tathāgatas of the ten directions, practicing on each and every one of the eighteen realms, all attained perfect and unexcelled bodhi; between them there was neither superior nor inferior. But you are inferior, not yet able to achieve perfect, unimpeded wisdom among them. Therefore I proclaim this to lead you merely to enter deeply through a single door. Once you enter the one that is free from falsity, those six cognitive faculties will become pure all at once."
