It can use these vehicles but does not get attached to them. By wrong identification the Self, which is pure Being, gets fixed, as it were, trapped in a net on the physical plane, for example, where someone has, perhaps, total addiction to drugs - he cannot help himself. You have to get the person to realize who is taking the drugs. When you find out who is taking the drugs, you can distance yourself from it, and the process of rebuilding the connection with the Self takes place. Detachment is detaching yourself from identifying with yourself as body, mind or spirit.
Many people suppress their emotions.
To suppress your emotions is just as bad as indulging your emotions. What you have to learn to do is to look at your emotions and not indulge them and not suppress them either. It is like creating a space between you and them. Most people immediately identify with their emotion, whatever it is. They have done so all their lives and so they take it for granted.
