Therapy is considered here as a process of restoring the way to sanity. But it is important to know what a sane life is. For the author it is a balanced yet creative state of body-mind in which our desire could conduce itself, at least hopefully, to the ultimate degree of the construction of a meaningful life or of the realization of its potentiality. The process of language appropriation and dialogical interaction are considered as essential here. For me this construction of a meaningful life, and therefore a life of sanity, consists of three levels: First, the representational and linguistic construction of meaning, as casting up from the movement of our body and the desire residing therein; second, the social co-construction of meaningfulness, in which we dialogue with significant others in order to construct together a meaningful world; third, the ontological level, which implies also an act of deconstruction necessary for the openness and the ultimate fulfillment of human existence in the Reality Itself.
