Where does a man reach while asleep? How does he eat when hungry? When thirst flares up, how does it satisfy it ? And where does the water consumed creates calmness?
How does it cry or laugh? Then what is worry and glee or elation? What is fear and what is love? What is cowardice and to what extent is dreadfulness?
Where and how does hiccups, belching, phlegm, yawn, sneeze, passing of wind, scratching of body and many other such-like things happen?
What is the nature of lust, anger, greed, attachment and pride? Similarly reality of truth, contentment, kindness and righteousness cannot be known. (623)
