Before Adam sinned, he looked nothing like you or I do today. When we look at one another, all we see is flesh and bone, but if you looked at Adam before he sinned, his appearance was angelic, transcendent, luminescent. The midrash says that he wore kosnos ohr, skin of light. When you looked at Adam, you didn’t see his body, you saw Adam himself; his neshama, his soul. When you look at a light bulb, all you see is radiant luminescence; only if you look closely can you make out the surface of the bulb. The same was true regarding Adam: he was luminescent; only if you looked very closely could you just make out his physical body. His body was transparent, with the outside loyally and fully reflecting his inner self. This is true beauty, where the inner and outer melt into a oneness, where the physical perfectly reflects the inner spirituality; where the physical projects something much deeper than itself. Beauty is the harmony and synthesis of different components, resulting in something infinitely greater than the sum of its parts.
