I love mandalas. I remember learning about them in Humanities in college. Basically, "mandala" is a sanskrit word that means "circle". They are beautiful geometrical designs, often brightly colored, and usually in a circular shape, but more than their physical beauty, they represent a deep meditative and spiritual journey, with divinity being near the center of the design. Mandala derived designs are used in forms of worship in Hinduism, Buddhism, Islam, and Christianity.
Certain forms of meditation include studying a mandala, and letting it take you on an internal spiritual journey. Other forms include drawing or coloring a mandala. Interestingly, this has been researched and results have been published in the Art Therapy Journal of the American Art Therapy Association (click the link to see a summary of the study results). In a nutshell, the study found that "structured coloring of a reasonably complex geometric pattern may induce a meditative state that benefits individuals suffering from anxiety." Basically, color a mandala when you are feeling stressed or anxious, and it might help you feel more calm and collected.
A few weeks ago, I printed off several coloring sheets (just google "free mandala coloring pages" for tons of options you can print at home). Last week, I pulled out my kids' colored pencils, sharpened them up, and spent a few minutes each day working on the mandala pictured at the top of this post. I did feel a reduction in my stress after coloring for 10 minutes or so. (Although, I should note, it can be kind of addicting because it is fun, and they are really beautiful. So, some days I probably spent much longer than 10 minutes.) The mandala I colored above can be found here on Color Pages for Mom.
Hope you have fun coloring! If you have kids, now you have something you can be excited about coloring with them! :)
