The article explores the possibility of reconstruction of the concept of subject out of the discourse of mystical experience. The novel forms of philosophical theories are proved to be homogeneous to the mystical elements of the general structure of religious systems. Postmodernist trends of contemporary philosophy promoting weak phenomena of human world provide the epistemological background for new vision of religious mysticism, which was always dominated by collective forms of religiosity and disqualified as too individualistic and esoteric. Apophatic morphology of speculative mysticism resembles the conceptual apparatus of deconstruction or negative dialectics. Therefore it can be effectively reinterpreted as philosophical locus of religion, which is congenial to absorb the novel philosophical forms and translate them into religious discourse. The mystical experience cannot be subjective, because "subjective" implies either privateness or disorder. We cannot say that mystical experiences are either ordered or disordered, because they have no parts to be compared and contrasted with one another or with the order of the natural world - only sequences of experiences can be ordered or disordered. But mystical experiences must be something, so if they are neither objective nor subjective, we have to create a new category - transsubjective - for them. Mystical intuitions about subjectivity without Ego are considered as preceding attempts of phenomenology, fundamental ontology and deconstruction to conceptualize the dynamics of becoming of subjectivity out of certain primordial form of subjectity. The necessity of new synthesis of philosophical and religious conceptions of subjectivity appears from the harsh controversies of contemporary world, which is losing the common order of meaning, very likely to face the demise of some common system of laws and rights. To reconstruct a mystical subjectivity by the means of today's philosophy is to hope for reconciliation of scientific ratio with religious fidelity in terms more appropriate to the reality we are living in.
