CASE 45. WHO IS HE? To Tozan, Master Hoen the Fifth Patriarch said, "Shakyamuni and Maitreya Boddhisattva, both are His slaves. Well, tell me: Who is He?" Mumon's Comments: Should you be able to clearly realize who he is, it would be as if you met your own father at the crossroads, as you do not have to ask your own father who he is. Do not use another's bow and arrow. Do not ride somebody else's horse. Do not discuss someone else's faults. Do not try to know some other person's business.
