Mandalas are sacred circles.
A mandala can be a reflection of emotion, a prayer, a celebration, a reminder, or simply a bit of beauty. The word mandala means circle or wheel in Sanskrit. Mandalas have been used for centuries by various cultures as sacred and meditational art forms. Catholic rose windows, such at that in the Cathedral of Notre Dame are a form of mandala, created to shine light into a church or cathedral to instill in the viewer the beauty and love of God. Buddhists have created two dimensional and three dimensional mandalas for centuries as a way of depicing the gods and the universe.
