What are mandalas and how can they be used for psychological purposes?

Mandalas are artistic representations organized around a center and have an ancestral origin present in all cultures.
The simple activity of coloring mandalas activates physical, mental, and psychological mechanisms.
Mandalas can help balance the activation of the right hemisphere of the brain, which is involved in creativity, artistic sense, imagination, intuition, and the global, and the left hemisphere, which is involved in sequential, precise, methodical, and detailed processes.
Mandalas can be used for meditation and can provide numerous benefits in various aspects of our lives, such as physical, psychological, emotional, creative, and spiritual.
