This paper reflects on the poetical elements present in mystical discourse. The idea is to highlight the poetical characteristics of mystical texts. In doing so, the article asks which the mystical elements of poetry are. Another question is also raised: if it is possible to talk about poetics of mystic, is it possible to consider the existence of a mystical poetic? Considering the mystical discourse as the result of an experience with the Sacred, is there a transcendental experience expressed in poetry considered profane? For the establishment of this poetic of mysticism, the texts analyses some mystical poems: a psalm from the Bible and a poem from a Brazilian poetry that does not belong to a specific religion tradition. The result of this analysis is presented as a possible poetic of mysticism. Furthermore, the aspect of transgression of the language, present in poetry, is shown as an expression of the mystic of poetry.
