The teaching which is written on paper is not the true teaching. Written teaching is a kind of food for your brain. Of course it is necessary to take some food for your brain, but it is more important to be yourself by practicing the right way of life.
Preparing food is not just about yourself and others. It is about everything!
To cook is not just to prepare food for someone or to cook for yourself; it is to express your sincerity. So when you cook you should express yourself in your activity in the kitchen. You should allow yourself plenty of time.
