Yes, the body and mind are two separate things, unfortunately the mind doesn't have a body that can work the way it imagines things and fantasizes. The body on the other hand fails when it wants to fail, and no matter how strong one's mind is, it basically cannot do anything except it's fit enough to carry the mind, so I think this is what makes the mind limited: it still needs the body to function and execute.

If we cannot actually take care of our body then there's nothing as can achieve, no matter how super imaginative we can be.

I wish you a speedy recovery Sir, and thanks for the curation
