This work is an interpretative essay of Plotinus' treatise "On Beauty." Through a careful analysis of the text, the author attempts to emphasize the moral and religious aspects of the aesthetic experience. According to Plotinus, beauty is more than the prettiness of things. It is the spiritual guide of the soul and the path towards authentic values. Beauty leads the philosophic mind from the attractiveness of the physical things to the discovery of the inner jewel of the pure soul and finally merges the soul into the abyss above.
