A Zen Master, Rinzai, was asked, ”What is your sadhana? What is your spiritual practice?”
He said, ”Nothing much, nothing much to brag about; it is very simple: when I feel hungry I eat and when I feel sleepy I go to sleep.”
The man said, ”But that’s what we all do!”
Rinzai said, ”There you are wrong – take your words back – because I have lived like you, I have both the experiences. I have lived like a robot – the way you are I have been – so I know the difference. You eat when you are not hungry, you eat because it is time to eat, you eat because the food is delicious, you eat because you are invited to eat. You don’t care what is the need. You sleep because it is a habit; whether you need it or not is not the point. And while you are eating you are not only eating, you are doing thousand and one other things – maybe making love in your fantasy. And when you are asleep certainly you are not doing only one thing, sleeping – you are dreaming. The whole night your mind goes on and on creating dreams upon dreams.
