CS:
As first port of call, I agree that this is sometimes indicated. Often, it is not. By the time many couples reach out for intervention, the dysfunction has progressed to a very serious place. There are many other factors that are outside the domain of the most well intentioned Rov. There are psychological and psychiatric conditions that can be involved. This is not the exception either. And the untrained will seek to focus on what would otherwise be good advice, while missing the forest for the trees.
I haven’t a clue about those unhappy people who went to therapy. There are unhappy people who have gone to therapy, and many who have not. Your use of this as a representative is connecting dots that are unrelated. There are mood disorders that are partially relieved by therapy, not necessarily making the person happy, but improving function. Might a dose of spirituality help them? Perhaps. But there are plenty for whom this is not the missing ingredient. Meanwhile, your maligning therapy as contraindicated except in a small number of exceptional cases is baseless.
I, too, use spirituality in my guidance for people. It is a precious tool. But it is often not the deficiency that is responsible for the condition, and it is also not always the cure. There were Gedolei Yisroel who had various conditions. Shall I quote the Brisker Rov ZT”L who had OCD? How about a few of the Chassidic Masters who had mood disorders? Were they not erudite enough or lacking in spirituality to overcome their conditions?
As I noted earlier, there are important roles for everyone. Rabbonim have much to offer, and many are quite perceptive and insightful. Anomg the frum therapists, there are quite a few that are quite learned. And there is much cooperation and collaboration among them. I would not dismiss the professionals as purveyors of goyishe values, nor would I consider the average Rov a competent therapist (the Rov, in all odds, does not claim to be a therapist either). Your generalizations are not supported by the facts. I do not challenge your experience. But that does not reflect accurately on the global scene.
