There are some who have built a character like a cherry:
outwardly soft, but inside there is a hard stone;
there is another character which is like a grape:
it is outwardly soft and inwardly soft;
there is also a walnut character,
which is outwardly hard and inwardly soft;
and there is a character like a pomegranate:
outwardly hard and inwardly with hard pips.
