There is a theory that I heard that resonated. The reason that some areas in the world are still so warlike is that their DNA is one and a half strands instead of two. Two strands of DNA are the bare minimum for survival. People are supposed to have at least 12 strands of DNA and that 12 strands is our more natural state.
If this resonates, here is a technique to assist the word in overcoming its warlike tendencies. In contemplation, look at the world and see the places that look gray. Then imagine knitting, weaving, or crocheting 12 golden strands where there is two strands. There is no need to direct it in any area. Just visualize creating 12 strands where there are two. Do this in your visualizations.
When you look at the earth again, see if any areas that were gray are now lit up more. Keep the intention of always uplifting the earth with your intention. When ever you think about it and are in a loving mood, visualizing knitting 12 strands together where there were two. Make them straight, even, loving and golden strands. When you look at the earth in visualizations, see it immersed in golden, loving Light and saturated in Love.
