The 'Margin of Freedom' within Repetition in Art

Fer states that "This trope of renunciation, of a retreat inward to spiritual essence [. . .] has come to dominate the way Martin is thought about as an artist." Applied to her art, such an inward retreat creates a series of internal frames of "meaning." Within these frames-- which further connects the concept to the art - we see that the literary device of interior monologue can be employed within the retreat. But is infinity and repetition used internally or externally? Or both? Or neither? What can be perceived by the observer and what can be perceived by the artist? Martin's art appears to challenge rigidity in conceptual and physical terms by pushing for hybridity and infinity within itself.
