Who Am I? Zen Proverbs

Keiji, a long-time Zen student, approached his master and said: “I don’t see how there can be any enlightenment that sets you free once and for all.
I think we just get ever greater glimpses of Buddha-nature, the vastness that is our true Reality. It’s an ever-expanding process.” The master, looking penetratingly at Keiji, replied. “That may be what you think. But what is your experience, your experience right now?” Keiji looked momentarily confused.
“My experience right now, Master?”
“Yes. Do you know yourself as Keiji, having ever-expanding experiences of Buddha-nature? Or do you know yourself as Buddha-nature, having the experience of Keiji?”

A desperate student approached the Zen master. “Please, Master, I feel lost, desperate. I don’t know who I am. Please, show me my true self!” But the teacher just looked away without responding.
The student began to plead and beg, but still, the master gave no reply. Finally giving up in frustration, the student turned to leave. At that moment the master called out to him by name.

“Yes!” – said the student, turning around sharply.

“There it is!” exclaimed the master.
