Other mandalas are meant to last longer. It will take more time for them to be swept away into the mists of time.
Mandalas are ways for people to share visually what is in their hearts at the moment of their making. They can be realistic or whimsical or abstract. There is no right or wrong when it comes to creating a mandala.
Today, I painted a mandala. I was thinking about the earth because it is spring. On the 13th of this month, I planted trees and I was happy to dig into the earth and to place a tree into it so that, eventually, it could give shade to someone. I don't think a whole lot about the future normally but, when I'm planting trees, I think about people in the future enjoying all of that nice shade. I was thinking about bird songs and leaves and sunlight and soil and worms and all of that stuff.
I was thinking about circles and shapes... and painting the negative shapes instead of the images... so I did... and here it is...
