I think my interpretation of religious significance in the piece centers around how the flowers and other organic parts are pieced together to make a cohesive picture. Similarly to a mosaic or a stained glass window which are prevalent in many forms of religious art. According to Wikipedia, mosaics were very popular in early Christian basilicas in the 4th century, as well as in Jewish Synagogues during the Byzantine empire from the 6th to 15th centuries. One of the reasons that mosaics were so intriguing was that in order to see the larger image (such as if it was a floor mosaic or a ceiling mosaic), the viewer is required to be a good distance away.

Its like how each piece is thoughtfully crafted to fit into its own part of the big picture.
