四十二章經 1.18

1.18

佛言：「道無形，知之無益，要當守志行；譬如磨鏡，垢去明存，即自見形，斷欲守空，即見道真，知宿命矣。」

The Buddha said: "The Way has no form; knowing it [intellectually] is of no benefit. What is essential is that one must maintain resolve and practice. Just like polishing a mirror, when the grime is removed, the brightness remains and one immediately sees one's own form. By severing desire and maintaining emptiness, one immediately sees the truth of the Way and knows past lives."
