‘Master Guling Shenzan returned to his home temple after years of practice. When he returned, his master said, “I have had no word from you for a long time. What have you been doing out there all his time?”
“I haven’t been practicing at all,” Master Guling replied, “I’ve only been walking here and there.”‘ (Quoted in Unfathomable Depths)
Without wishing to give away the plot, it may be that Master Guling is hiding his light under a bushel, though it takes his master a little while to figure that out.
