This is the nature of that type of mind. It’s not that the whole mind is like that, but if the worry mind is there, the mind will worry about whatever. The stories will be worry, worry, and worry.
If the fear mind is there, then the mind will be afraid of this, this, and this. Everything that comes, the mind will have something to fear.
It’s the nature of that type of mind. So, when worry mind is there, it will worry; if fear mind is there, it will be afraid. If happy mind is there, it will be happy; if sad mind is there, it will be sad.
It’s like at night, usually the mind is already scared of the dark. So, when anything happens, we don’t really know what happens, we will think that it’s a ghost.
