Whereas the Body is a physical entity, the mind is too complex to understand. Definitely it is not a physical entity like our body. We can consider it a metaphysical thing. Yet it is a fact that they are interconnected. The mind resides inside the body. The condition of one influences the other. Everyone must have heard things like that if the mind is strong then it has a positive effect on the body. The mind is more powerful and directs the body actions most of the time. If the mind is strong, it can make the body achieve the unimaginable.
I think our personality is the sum of our body and mind. I can cite an example. When old age comes, the body begins to become weaker, some people try to compensate for this loss by making their mind strong. They can become more aggressive in mind.
These are my views and can be at variance with others.
