華嚴經義海百門 1.93

1.93

三、修解行者，謂於塵處，悟達理事、色空無性之義，是解也。理解在心，是智也。行通為行。若行心作真解、作俗解，非名解也；不作一切解，解心無寄，是為大解也。又若起心作凡夫行、作聖人行，亦非行也；不作一切行，行心無寄，是名大行。行非是過，由心起作；解亦非過，由心住著。常無住著希望，乃是真解行也。

Third, "cultivating understanding and practice": at the dust mote, awakening to and penetrating the meanings of principle and phenomena, and of form and emptiness being without intrinsic nature, is understanding. The understanding of principle being in the mind is wisdom. Free penetration of practice is practice. If the practicing mind forms an understanding of the true or forms an understanding of the conventional, it is not called understanding; not forming any understanding, with the understanding mind having nothing to rely on, is great understanding. Furthermore, if one arouses the mind to perform the practices of ordinary beings or perform the practices of sages, this is also not practice; not performing any practice, with the practicing mind having nothing to rely on, is called great practice. Practice is not an error; [error] arises from the mind producing activity. Understanding is also not an error; [error] arises from the mind dwelling in attachment. Being constantly free of dwelling, attachment, and expectation is true understanding and practice.
