Well, your comment triggered a little research, because I don't really know enough about mandalas to answer you. All I knew was that the word mandala means cisrcle and as I said in one of my oldest posts, I started to draw them just because I loved doodling so much and I found that drawing mandalas relaxes me. So I googled a bit, and I find this description to be the closest one to my way of seeing it:

'The design of the mandala is supposed to be visually appealing so as to absorb the mind in such a way that irritating thoughts are unable to get through and a spiritual essence surrounds the individual observing the mandala, which in turn allows the individual a higher consciousness or awareness, almost as though being hypnotized. This allows the busy mind to take a break while the creative mind is allowed to run free.'

Anyway, this comment is already way too long, but I geniunely wanted to answer you in a way that I can answer myself as well :D Thanks for your comment!
