Here is one of my mandala attempts. Meditating on these images can produce some wonderful effects and I find it more enjoyable that focusing on a candle flame or similar object. Have you tried meditation? Have you any hints to help deepen the experience.
One trick that really helps me is to make sure my back is straight and I am setting as upright as possible.
Let me know if you try meditating on this image and how it went. Good meditating!
