No "I", No "You"

One day a student asked Zen Master Man Gong, "Where is Buddha's teaching?"
"Right in front of you." Man Gong replied.
The student said, "You say, 'in front of you', but I cannot see it."
"You have 'I', so you cannot see."
"Do you see?" the student asked.
Man Gong answered, "If you make 'I' you cannot see. But if you make 'you', it is even more diffucult see."
The students asked, "If I have no 'I', no 'you', then who is speaking?"
The student was then instantly enlightened.
