Abstract
Assuming along with Heidegger that philosophy is ontology of its object and phenomenology by its method, the intention is to present some guidelines for the hermeneutics of mystical poetry; specifically for the Cántico Espiritual. For this purpose, a description is essential to poetry, intended to clarify why this is so pure spoken, followed by the characterization of mystical poetry. Later I show that the ineffability of mystical poetry is a feature that belongs because this is original word that establishes a way of being in the world, whose meaning is the union between man and God. Finally, in response to warnings that St. John of the Cross makes in the prologue and the annotation on the interpretation of mystical texts, I think about the conversion temple as emotional disposition installed in which he begins the search for the Beloved
