You put a key in a lock and the door opens.  Only one shape fits the hole of the
lock.  Only one.  But you can fiddle with the lock a bit and
perhaps force your way in.  Are not
humans like that?  There is one key to
true spiritual happiness—to joy—and that is love … being the presence of love,
sharing the self as love.  But the human
tries so many other ways of prying open the door, including trying to force
others to open it for them.  You were
born with the key.  You merely need reach
into your own heart and find it there and doors will open left and right.
