Art and religion has many regions of overlap. It is an organic interaction that leads to much richness in cultures. One can just think of all the Byzantine art as an example.
Among the forms of art associated with Eastern religions, one finds the mandala. It is an abstract pattern, usually circular in design and often has some symmetries. Its meaning is some way associated with the universe, however, there’s more to it. Part of the whole significance is the actual creation process of a mandala. A person would tend to start from the centre and work his way outward. In this way, it represents how the individual is being connected with the universe. At least, that is what I understood from what I read about it.
These days one often encounter mandalas in various non-religious contexts. It may even be regarded as a theme in abstract design. One can for instance notice them in adult colouring books.
It is fun to makes one’s own design for a mandala and to let the creative juices flow. The one above I made using POV-Ray. One can play with the colours. Here I decided to make it look like a metal wire construction. The reflection at the bottom did not come out so nicely.
