I think a mind is purely a mechanical function of our complex brains. It is given quite an abstract description as of now, but I believe as science progresses in the future, the concept of the mind will be broken down into different physical categories and explanations as to how exactly it functions.
It will, in the future, be calculated, duplicated, and created. Nothing spiritual about that. The mind is in my opinion a purely physical phenomenon that is just waiting to scientifically explained. Just a part of the brain. I think that no natural-made creature has a mind to the same degree as us.
To sum up; I don't think there is anything spiritual about the mind, except for that it is the sole tool that allows the soul to communicate and interact with this physical realm.
