Eknath Easwaran's Commentary
You are what the deep faith of your heart is. If you believe that money is going to make you happy, then you will go after money. If you believe that pleasure will make you happy, you will go after pleasure. Because, “as a man thinketh in his heart, so is he,” not as he thinketh in his head. There is a vast distance from the head to the heart. In the Greek and Russian Orthodox traditions, they say that whatever spiritual knowledge you have in your head must be brought down into your heart. This takes many, many years.
