A Zen Story. Open your Mind.

An American scholar in Zen Philosophy goes to meet a Japanese Zen Master.
The American has a lot of knowledge about Japan and Zen philosophy.
He wants to meet the master. The master's attendant comes and asks the visitor, "Would you like some coffee?" The American replies in the positive. The attendant brings a cup of coffee full to the brim, then he brings a jug of coffee and starts pouring the coffee in the already full cup. The coffee spills over and within minutes the jug is empty.

The Zen Master comes and tells the American. "Son, empty your mind, if you want to learn. Right now, your mind is full of knowledge, ideas, thoughts, observations and, unless you empty all those, your mind will be like the cup of coffee, full to the brim and not able to take anymore and the jug of my knowledge would be emptied without you having learnt anything. Empty your mind and let it open to wisdom."

There's a saying among prospectors. Go out looking for one thing and that's all you'll ever find. Always be passionate and inquisitive about things. Open your mind to wisdom.
