The antinomic installation of everyday life and life in the later works of Marina Tsvetaeva are presented in the article. The author, referring to Tsvetaeva’s works, highlights the importance of conflict of everyday life and being and shows its «specific» semantic value in Tsvetaeva's poetry. Antinomy of life and existence is modeled through the multiple ontological oppositions of «down – up», «earth – sky», «body – spirit» and others.
The author proves that Tsvetaeva’s conflict of everyday life and existence can be solved very peculiar. Firstly, the romantic mismatch of the world of the earth, associated with a lie, to the world of heaven, which is essentially the highest truth, lies in this conflict. Secondly, an important component of this conflict is the love line, which turns out to be some a sort of psychological key to conflict of everyday life and existence.
