“We have a mind-condition that makes us itch for two types of pleasure: pleasure of the senses and pleasure of the ego. When our senses are pleasantly stimulated, as when we eat something tasty, or our ego is pleasantly stimulated, as when we are praised for something we did, we feel joy, which is good. What is even better is if we can feel joy independent of sense or ego pleasure. For example, when we are eating chocolate, we experience joy, and when we are just sitting there not eating chocolate, we still experience joy. In order to do this, we train the mind to access joy even when it is free from stimulation. This is also the secret of raising your happiness set point.
