A monk asked Chao-Chou,
“If a poor man comes, what should one give him?”
“He lacks nothing,” answered the Master.
Everything that you need, you already have. We do not need anything outside ourselves to be complete. This is an expression of containment, of self reliance. We just have to accept who we are. If you are not secure in yourself, no one can give you security. If you are not happy with yourself, no one or no thing can give you happiness. It is not necessary to seek fame and fortune to achieve contentment.
It is also not necessary to study acting to be a good actor. If you know who you are, you will be a good actor. If you are running from yourself, no amount of training will help you. With that said, I believe that every theatre artist should constantly study. Different styles and techniques will always make you more competitive. Just realize the thing that will make you a success is who you are.
