I was thinking about how one of the things that is so crucial to health and growth is healthy narcissism, or in other words, the capacity for self-love. Much suffering stems from problems in that specific area, whether a complete lack of the capacity or distortions in it. And one thing a therapist does tend to do is model healthy narcissism, which just by being presented continually to the client has the possibility of being internalized. This is an indirect form of love, but there are some therapists that are aware that this is part of what they are doing, whether they label it or describe it in these terms or not.

Here is what I came across just scanning:

"Whatever complaints the patient may have," says Fromm, "whatever symptoms he may present are rooted in his inability to love, if we mean by love a capacity for the experience of concern, responsibility, respect, and understanding of another person and the intense desire for that other person's growth. . . . Analytic therapy is essentially an attempt to help the patient gain or regain his capacity for love" (Psychoanalysis and Religion).
