This is the DBT definition that I got:

The purpose of the DBT skills in all four skill sets is to help the client get into a state of mind referred to in DBT as wise mind. Wise mind is the middle ground in the dialectic between rational mind and emotional mind. To be too far on the side of rational mind would mean focusing only things such as facts and figures; ignoring and supressing emotion. To be too far on the side of emotional mind would mean being so blinded by strong emotions that one would not be able to consider the facts.

Once can either be really rational (lacking in emotion) or really emotional (lacking in rationality) and thus, a balance is called the Wise Mind. So... I think pdoc wants me to get in touch with my "feelings" so I won't keep having this emotional constipation.

I'm kinda looking fwd to this therapy since it would be very challenging - as it sounds.
