I read that creating a Mandala is a spiritual and meditative process and I definitely experienced this when creating it. However the significance of Mandalas are their impermanence. However in nature they are in a permanent state. By burning it and 'returning it to nature' is it really gone? Is it really impermanent?
What I found interesting was that the flame travelled in a circular motion starting from the centre working its way outward then returning to the centre again. This is the natural path/progression that Mandalas follow and create.
