Living a useful, productive and helpful life can mean different things to different people. If it is based on a moral compass that espouses charity, generosity, no harm to others, and no harm to oneself, then it is most likely the correct way of living. However, there is more to correct living than these moral compass points, although they are by no means unimportant.
Just as feng shui is based on natural forces of cosmic energies that have their own logic, flow and progressions, so do peoples' existence on this world. For us, the natural energies, whether positive or negative, flow in a circle from the mind, to the body, to the soul, and back to the mind. That is, the mind controls and feeds the body, the body feeds the soul, and the soul then feeds the mind. If the mind, body and soul are in harmony and balance, then there are sustained positive energy and happiness.
