It is a visual aid for concentration and introvert meditation leading to the attainment of insight and also for activation of forces culminating in Sisshi supernatural forces. The Mandala is the graphic representation of this process.

There are many types and varieties of mandala represent the "sacred place" properly enclosed in multiple circles of flame, Vajra, lotus, and then the inner squares to reach of the deity of the mandala.
