In this study I examine the concepts shown by Juan Emar in his reflexive-character writings from the '20s (Cavilaciones (1919-1922) and articles on art (1923-1927)). These concepts build up a systematic semantics net that allows to propose a global interpretation of Emar's work understood as a unit of sense. This conceptualisation is an occultist metaphysics that refers to the individual-world relationship as a cognitive and constructive-creative relationship according to eurythmic poetics, the base of which is a theory of equilibrium governed by numerical-geometrical laws. Here, I claim that there is evidence of this constructive system working in Emar's writing practice of fiction texts from the '30s (Ayer, Diez and Umbral).
