No doubt, there are four categories of personality. The first one is the person whose personality is likened to walnut, the other is like grapes, the other like date, and the fourth is like pomegranate.

The date-like personality is soft outside and hard inside. As soon as one takes a date in the mouth, as soon as the seed comes under the teeth, one has horror of it.
And then there is the other personality which is walnut-like. There is a hard shell, hard to penetrate. But when you know the person more, it is like breaking the walnut, and there comes a nut which is soft.
And then there is a pomegranate personality. It is hard outside and hard inside. The pomegranate is hard, the cover is hard, and at the same time the seed inside is hard too.
And then there is the grape personality which is soft outside and soft inside.

You will always find these four classes of persons.

The personality of one who is hard outside is repellant first, but in the end you will become his friend. Therefore, he has always lost his friends. You understand him only when you come to the inner being of this man. Therefore, he will always lose his friends.
And the one whose personality is soft outside and hard inside will at once attract people, but they will not stay with him. They will stay for some time, but then they leave him. Then they know him and go away from him.
And the person whose personality is hard outside and hard inside is isolated in this world. This is not the place for him. Everyone will want to keep away from him. And after some time he will find himself in a difficulty.
And the one whose personality is soft outside and soft inside naturally will be most magnetic. The grape is the most attractive fruit.
