Observing closely, effortlessly...
 one comes upon a certain feeling of:
   comfort   ease   contentment...
a measure of:
   relaxation   effortlessness   satisfaction...
and as one becomes more aware of this:
   pleasure   delight   happiness...
one comes upon a state of deep:
   enchantment   joy   easiness...
a condition of quiet:
   calm   restfulness...
               and   repose...
