This article studies the concepts of pleasure principle and death instinct. The pleasure principle is represented as a borderline function that designates the bases of dynamic unconscious and the sense of being beyond which lies systemic, unsymbolised unconscious. My study references the Finnish view of the death instinct as presented in Ikonen and Rechardt's theory and the French view mainly read through Lacan. The death instinct is seen as a metapsychological concept that allows us to approach systemic unconscious settled beyond the pleasure principle. I put forth that Ikonen's concept of hypercathexis seems to some degree parallel with Lacan's concept of the Other jouissance. I suggest that the possibility of approaching one's own authentic being as a limit beyond the pleasure principle, is meaningful to the experience of authentic individuality. On the other hand, the instinct is by nature traumatising, and too much raw touch with it threatens the continuity of the sense of being. I also present that through this metapsychological framework of thought, the psychoanalyst can participate in the process of the analysand's developing self-observation in such a way that the analysand is not left too alone but still retains the freedom to develop into their own self.
