Medication or meditation
A mandala or "wheel of life" is used for ritual ceremonies and meditation. A mandala has a round pattern that symbolizes the cosmos and is used for achieving inner peace and mental stability.
A mandala, and in particular the middle, can be used during meditation as an object to focus. The symmetrical geometric shape ensures that attention is automatically focused on the center.
