Throughout history symbols of political or religious importance have been seen in the clouds. In A.D. 312 when Emperor Constantine was marching against the army of Maxentius at Rome, both he and his entire army saw a shining cross of light amid the clouds.
It was said the cross contained the Greek words "By This Conquer". Later that night Christ appeared to Constantine in his dreams bearing a cross in his hand ordering Constantine to have a military standard made in the same image.
Under this standard his outnumbered army was victorious. Down through history entire military battles have been witnessed in the clouds.
Some of the UFO sightings have in fact turned out to be disk shaped cloud formations. Generally cloud scrying is done on days when cloud conditions are good.
Having too few or too many clouds is no good for scrying. The best is when the clouds are thick.
Find a nice location to lie down and just relax. Try not to focus on any one cloud but rather allow the clouds to drift across your view.
Visions cannot be forced, they will come naturally when the time is right.
