Ma-tsu and the treasure
In the 8th century a student went to visit the great master Ma-tsu.
The master asked, "Why have you come here?"
And the student replied, "I seek enlightenement."
The master said, "Why go out to see it and forget that you have the treasure already? I have nothing to give you."
The student said, "But what is my treasure?" The master answered, "It contains everything and lacks nothing. There is nothing to seek outside of yourself."
There are actually a few similar stories about Master Ma-tsu. I really like this one. The student has come asking for some kind of secret to be revealed, a key to Enlightenment.
Ma-tsu is telling him there is no secret. We all have the treasure inside and it's our true nature. Enlightenment is not something to seek outside of ourselves.
That is the message.
