Before he was himself a master, Hakuin went to master
Shoju to demonstrate his knowledge of Zen.
When Shoju asked him what he knew, Hakuin pretended to
vomit and announced, "Anything I can find I will expel from
me." Shoju, however, was unimpressed. He tweaked Hakuin
firmly on the nose and said, “What is this? Have I not found
something after all?”
The master showed Hakuin he still had a concept of I and me. Truly a burden.
