I think there must be a balance between mind, body and soul if you want be able to function correctly. Personally I'm striving for balance. What's your opinion? Are there anyone balanced there?
I agree completely and have been close to achieving that balance previously, but am far from it presently. Working on it!
Many years ago, I had training in a counseling technique which uses the acronym PIE, which stands for Physical, Intellectual, Emotional. The goal was to strive for a balance between the three. Just another way of stating your premise without the use of the word "soul."
I take a daily anti-depressant that keeps me going but I'm not really balanced. Sometimes I take a valium and I really enjoy that mellow feeling. I was religious too for many years but that never gave the spirit of peace it promised. I suspect, with no proof, that some balance must be bought by compromise with other people - in other words selling a part of yourself to buy smoother relationships with other people.
