What Binds You?

One day a Zen master gave a lecture, an afterwards a youth came forward and asked him,
“What kind of mind is the Buddha mind?”
“What kind is your present mind?” asked the Master.
“Right now, I do not have any mind” the youth answered.
“Since you do not have any mind, how can you ask about Buddha mind?”, the Master returned.
“Master, please show me the way of freedom.” the youth asked.
“What binds you?” said the Master.
“Nothing binds me” answered the youth.
“Since nothing binds you, you are already free, so why do you ask for the way of freedom?
