I have discovered that it is necessary, absolutely necessary, to believe in nothing. That is, we have to believe in something which has no form and no color - something which exists before all forms and colors appear.  This is a very important point.  No matter what god or doctrine you believe in, if you become attached to it, your belief will be based more or less on a self-centered idea...  In constantly seeking to actualize your ideal, you will have no time for composure.  But if you are always prepared for accepting everything we see as something appearing from nothing... then at that moment you will have perfect composure.
