When we accept an idea and reinforced it by repeating it or using other references as support, it will then form a Belief.
One metaphor we could use to describe belief is:
The mind is like a cement. Ideas are written on it. The references that support this idea is like a fan used to fan the cement. The more supports your mind comes up with, the faster the fan swings and the quicker the cement hardens. Once it is hardened, it has formed a solid belief that is not easily breakable.
Now, you will need some tools such as a hammer to break it. It needs powerful force to do so because it is no longer fresh and soft.
