As another posted pointed out, I didn't see that the article specifically said to get into touch with your therapist's feelings, but I also think that understanding what people are feeling is something most of us think we're good at. So we try to do it, whether it's "my therapist doesn't care about me" or "my therapist wants to put me on a greyhound bus to the state line" or "my therapist thinks I'm special" or "my therapist is mad at me." etc, etc. Sometimes it's intuition that is driving our perceptions of others, sometime's it is an empathic response that allows us to understand what people are feeling, positive or negative, other times we're inserting our past and/or distorting the present or in my favorite terminology, following a script rather than being rooted in the present. So I think that what we think about the therapist's feelings and thoughts can absolutely be important to understanding what's going on with us because . . . people impact each other, and as that article emphasize, our therapist takes cues from us, tries to follow us. Then we react to how they are following us.

I don't get the sense that you mean the content of the therapy should focus on the therapist's feelings, but I do see the relevance of the therapist in the room. But I also like the article because I think it points towards, as you said, not just endlessly talking about feelings, but about the meaning surrounding them and working towards the changes you want for your life, which often start but rarely end (for me) with understanding my feelings.

I would think you could have a good discussion with your therapist by bringing the article in and talking about what you took away from it. Likely there are some important clues in your reaction to it. For example, your desire to understand if there's anything you do that makes her job more difficult, which strikes me as a very connected way to ask a more simple question, how do I get in my own way in reaching my goals?
