Making and then destroying mandalas created from colored sand is a Tibetan practice. You can do the same with colored sand from your local craft store and a container such as a tray or box top lid that will successfully contain the sand.
You can also draw, paint or create the mandala from other materials. For instance, you can tear different colors of paper and arrange them into a mandala pattern.
Typically, a chanting session would be done before you start your mandala work to get centered. Then, you can use whatever meditation feels best for you. Simply create the outline of the mandala, start from the inside and work outwards.
Destroying your work is optional and can be symbolic and cathartic.
Painting and calligraphy to help focus the mind have been popular meditative pursuits for centuries. You can use a variety of different size brushes, paints, papers and allow yourself to observe what comes up as you create. There are calligraphy tutorials online that you can use if you’d like to learn more about this art form.
With creative meditation styles there is no room for judgment or criticism because it is not about being an artist. This type of practice will create beauty of a stronger inner core, a stimulated yet relaxed mind, and a connection to your source.
You can use your smartphone to practice this meditative style when you are out in public, or carry a notebook and pens with you.
