The comprehension of human being specific rule in German existentialism (M. Heidegger, K. Jaspers, M. Buber) is considered in above-mentioned works. The philosophical-anthropologic problem of human essence is considered here widely on the background of historic experience of philosophical-anthropologic thought and its predecessors (S. Kierkegaard, Fr. Nietzsche, Ed. Husserl and other). In particular, it is shown that the research of human essence profound layers in German existentialism coryphaeus lead us to analogous view-points that took place in Oriental esoteric thinking (Dzen-Buddhim, classical Buddhism, Yoga's doctrine and other). The author supports his view-point that the tendency of human essence eternal problem investigation is dominant to founders of XX century's German existentialism, as D.T. Suzuki, known representative of Dzen-Buddhism and existentialism simultaneously. The same situation is in the doctrine of Yoga.
To German existentialists the mystery "essence" of human is being, existence, and internal existential freedom. This is called as the own, genuine "self" (eigentliche "Selbst") in M. Heidegger's fundamental ontology, that is founded on the "temporality" and "forestalling resolution". This is treatment of "embrace" ("Umgereifende") achieved by existential sparkling in K. Jaspers' "existence philosophy", and single human's deepening in his primary treatment, "Me - You" foundation, primary relationship to God by M. Buber.
In author's view-point, fundamental ontology (M. Heidegger), existence philosophy (K. Jaspers) and "dialogic philosophy" (M. Buber) in their essence and spirit are philosophical-anthropologic doctrine "dressed up in ontological clothes".
Human "essence" is "mystery of mysteries" to German existentialism of XX century. Existence, as an origin of human mind and actions, is indirect. It is incognizable for the rational mind, subject-object split mind. Existence, human internal essence is inconceivable, "unattainable" only by logical-scientific mind. Getting over alienation, human's "leap up" to himself is possible only by the co-operation of ratio and irrational ways.
The analogous situation is found in Oriental esoteric view-points. The human's self cognition and self perfect is achieved only by co-operation of these two abilities - both the intellect and intuition guesses. The evidence is a sudden spiritual sparkling (Sator) in Dzen-Buddhism, Nirvana in classical Buddhism, Samadhi in Yoga, Absolute Samadhi in Dza-Dzen and other.
In author's opinion, this analogous, astonishing organic relationship of German existentialism and Oriental centuries-old wisdom can be explained by many reasons, the main among them are the general existential nature of human and, certainly, European and Asiatic direct cultural-philosophical relationships in the last centuries. The main idea carried out in the above-mentioned works shows that the analyzed doctrines can be considered as the best samples of humanity philosophical-anthropologic search, though; they can't fully complete possibilities of future investigations.
