You are born with about seventy-five percent of your life predetermined by your past. You will make up the remaining twenty-five percent. If you yourself, through your own free choice and effort of will, do not determine what that twenty-five percent will be, the seventy-five percent will make the twenty-five percent for you, and you will become a puppet. That is, you will be ruled absolutely by your past, by the influence and effects of your past tendencies. This is why spiritual training is vital. It takes into consideration not only the seventy-five percent of our lives that we already are, but also designates the methods to mold the brand new twenty-five percent that we ourselves are going to create by the exercise of our freedom.
