I am not sure that that is the reason why we are speaking at cross purposes. No, basic trust does indeed exist in children who are well-parented. It is an ideal that can and is met. I should have realised that you were talking about patients. Naikan seems to ignore this.
People have good and bad experiences.
It is only natural therefore that a balanced therapy should recognise that people in therapy are likely to be on the bad side of the balance. It is not psychoanalysis that is imbalanced, but patients. Naikan on the other hand, refuses to accept that those who are suffering in the present are those that had a bad time. Despite this, it asks them to realise how much of a good time they had. Therefore, it is not balanced.
