Perhaps in the same way that "pig" is the animal and "pork" is the meat.
I.e. it seems you are just using different names for the same thing but in different context.
And not describing any actual difference.
What do you see as the difference between "soul" and the "mind/body", other than the context in which the terms are used?
Before I go further, can you answer this question...
What is the difference between an orange and it's taste?
