I didn’t even know what a Mandala was so I looked it up. Here it is in case you don’t know. They are diagrams for focussing the mind – perhaps for peace or meditation practice.
I found these on a site called Subtlebody Images. Marilyn from the site offers the ones I have uploaded here free to share and these are below in the slide-show. However, there are some great interactive and moving ones (that remind me of a kaleidoscope) that are totally beautiful. I went through lots of these like an excited child with a new toy! Hope you enjoy as much as I did. If you go onto the home page, they are listed on the right under MANDALAS.
