The Visual Ray Revisited

I love this article.
We have been having wonderfully hot days here which we have been enjoying so much - being outdoors, in the garden, walking by the river etc.
It is tempting to assume because it is hot and sunny that the sky is blue. But you look up and the sky is almost white - even though the sunlight through this haze is strong enough to cast shadows of the objects on the ground. Years ago we never hasdlike this. Proper clouds do not work like this.
Anyway I love this article which reminds us how strong our consciousness is compared with any malevolent forces out there.
