laughter

The mind is the human organ that excretes fantasy.   

fan·ta·sy noun \ˈfan-tə-sē, -zē\
: something that is produced by the imagination : an idea about doing something that is far removed from normal reality

Silent meditation reminds us of this fact. This is why meditators, from time to time, break into spontaneous laughter while practicing.

peace on you,
