This paper brings to the fore the distinctive phenomenon of the extreme, or of life's tendency to absolutize itself, which Husserl, his assistant Eugen Fink and the Japanese phenomenologist Kitaro Nishida have all attended to. This analysis represents the idea of a phenomenology of the classic Chinese conception of Xin-Xing (mind-nature) that aims at making visible phenomena in terms of interaction between different traditions and gaining a deeper understanding of the essential structure of human beings.
