With the main motif of light, which stands, both in the physical and psychological construction of man, as an allegory of truth, and thus transcends the very matter of light, through considerations under the guidance of mostly Thomas Aquinas, one encounters a conflict of contrasting concepts; activity-passivity, light-darkness, vitality-mortality, and through generally known conceptual pairs a view of the generality of human nature is created in which, to a certain extent, man himself conditions the state through the movement between these concepts through surrender and will. In order to clarify the concept of tradition in modernity that stands behind ancient materials translated into the present, it should be recalled that we see the future by looking into the past, and thus we transform the very idea into a reaction to a past action. Lux Aeterna, Eternal Light, stands behind man's continuous striving for knowledge, and emphasizes the importance of constant attention and vigilance.
