Inscendence can be reached without imagination, but if art or imagery is involved, a so-called generative imagination is crucial to have a more direct and participative way of engaging, of creatively regenerating or co-generating what one is confronted with.
In other words: a static, photographic perspective cannot resonate with the dynamic actuality of the world (and the artwork, if applicable).
In music, the flowing, ineffable qualities are usually obvious and easy to step into, and in video too to some extent (but the subject-object dichotomy is much more present usually), triggering resonance and fine sensibilities within the listener or viewer. This flux resonance can also be triggered visually, by means of the body and generative imagination.
