The article presents an analysis of Leonid Aronzon’s poem «Message to the Clinic» (1963). The text is analyzed for the functioning of multi-level repetitions; cultural context – in terms of the poet’s religious identity and the mindset of uncensored poetry of the 1960s; the subtext – regarding the biography of Aronzon, as well as the trials of Joseph Brodsky and Vladimir Shveigolts. The total repetitions in the «Message to the Clinic» organize the poem composition and, contrary to expectations, do not simplify, but consolidate its semantic structure. In the poem it is necessary to single out several significant levels at which one can observe realization of the repetition principle as augmentation of meaning. Firstly, this is the level of vocabulary at which the repeated word expands its meaning to «hieroglyphic» one. Secondly, this is the level of syntax, where the repetition of figures and the variation of equivalent constructions contribute to the formation of identical rhythmic-intonation blocks, as in suggestive speech genres such as spells or mantras. These levels, in turn, are closely connected with the development of the text composition: the «unique», not repetitive, becomes significant. Thematic variation also affects the development of fundamental images, creating spatial-temporal polyphony. In addition, the totality of the repetition principle makes it possible to establish clear semantic links on large intervals of a specific poetic text and in general in the space of Aronzon's poetry. The form «Message to the Clinic», its religious and mythological themes, as well as the appellative orientation can be interpreted through the prism of 1) New Age ideology, 2) so-called «poor religion», 3) specifics of the work of the Soviet psychiatry with the literary underground of the 1960s.
