One must be clean themselves before ever being able to contribute to the world in a positive way. There are medical cleanses out there but to have a spiritual cleanse is most important. That means having a pure heart and pure good intentions in how you contribute and affect others. Most folks are not selfless, but selflessness goes a long way in this effort. A spiritual evaluation is healthy and good. Tears are therapeutic and a self analysis is necessary from time to time. Doing the same thing over and expecting different results does not work.
