Mandalas are immensely complex symbolic structures, with many layers of meaning and beauty. Although very beautiful and aesthetically pleasing, mandalas are meant for religious use, and are not intended as museum works of art. It is only in recent years that the Dalai Lama has permitted mandalas to be made in public, as a means of teaching about Tibetan culture.
The teaching of the mandala is passed through an oral tradition started by Shakyamuni Buddha over 2500 years ago. It has been passed down over the ages and can be traced back through the lineages to the historical Buddha.
