Deference is made to the decisive significance within the relation between the self and the ego. Experience indicates that the self, which guides the psychical process of growth from birth becomes manifest at the age of two - three years. I consider this manifestation to be the most important event in the development, since experience has shown that this event constitutes the starting point for a healthy ego. Where the manifestation of the self has failed to take place at all or has been inadequate (especially because of a faulty mother-child unity), an attempt must be made to constellate this unity in the transference situation, under the protection of which the omitted development can be made up.
