Hailing from the cultural realm of India, the mandala signifies in its original sense a sacred circle. It serves as a meditation aid and at the same time reflects an ancient symbolism of strictly geometric basic forms accompanied by an interpretation of its sacred content. As an expression of the awareness of higher affinities, the symmetrically arranged geometry can be found in a variety of pictorial works and the architecture of various epochs and cultural realms, for example in medieval book illumination, the floor plan of the Blue Mosque in Istanbul, in Kazimir Malevich's Black Square, or in various objects of the indigenous peoples of Africa,
