Perhaps I have been practicing too much this week. There has not been a single cloud in the sky in 3 days.
Since I have been posting this on a public forum, I have been awaiting a ceast and desist request from The Society For Cloud Preservation (SFCP).
Here are some more observations based on further practice (I hesitate to say experimentation, because I have not yet fully designed an experiment that would meet the scientific method). I have attempted to disapate more than 100 clouds in the last 3 weeks.
Once the cloud I was focusing on did not disapper but the cloud next to it did. Once the cloud I was focusing on got larger not smaller and eventually I had give up on that cloud. Then I picked another cloud nearby and did make it disappear.
I have also spent hours watching the sky to see how often a clould would disappear without me willing it to. I have not yet seen cloud disappear that I did not intend to disappear.
Clouds at lower ceilings are easier to dissapate than at higher ceilings. Smaller clouds are easier than larger clouds. For very large clouds, if I make is disapate, another cloud tries to re-form in another area. I suspect the moisture is still in the air, just no longer visible. It is easier to disapate clouds when there is more blue sky available but it can also be done if the the sun is not at all visible through a layer of clouds.
I strongly suspect this is a skill anyone can learn, but it probably requires a certain state of mind. Here is some context about my state of mind. I have been meditating two times per day for 1.5 years for 25-45 minutes per meditation. During my meditations, I most times reach a state of non-thought. A better definition might be no words or visualizations during my meditations. Recently I also often find this state of non-thought present at other periods during my day, although it is easier to achieve when I am in nature walking than sitting in my office surrounded by paperwork and computers.
Occansionally I reach a state of mind during meditation that I can only describe as transcendant. I have never read words that I could point to and say "yes", it was like that. My general state of mind has also been trasformed. As an example, I rode my bike to work two weeks ago. When I was ready to go home, it was raining. By the time I left, the rain had turned into a deluge (1.5 inches in 1 hour). I enjoyed the experience so much, I started laughing. And I continued laughing until I got home. I even detoured and took the long route home. I don't think I could have laughed in the rain one year ago.
