Mandala is a Sanskrit word for "circle," and a mandala design is a
circular design with repeating motifs in it. Some mandalas are very
simple, while other mandala designs are quit complicated and intricate.
A mandala coloring book can be quite complex, and it can be a very
soothing thing for an older teen to receive. An older teen is too old
for cartoon characters, but they will be drawn to the intricate and
spiritual nature of mandalas, which allows them to create art that can
be hung up on their walls.
