I have perhaps ten or so ancient rare books I’ve collected over the years — from China, India and Arab Sources — that deal with special cloud formations that foretell of coming earthquakes or other events. Sometimes these atmospheri c phenomena foretell defeat in battle, death of a ruler, the birth of a great man, and so forth.

Here are pictures of an earthquake cloud, one of these special phenomenon. Very rare …

You can find mention of such things in the Indian classic, Brihat Samhita. We don’t just discuss Meditation  but other phenomena on this site related to Qi (chi) and cultivation. For instance, when a master becomes enlightened and reaches a certain level of meditation, a purple stream of chi often shoots in the air which can only be seen by people with supersensible abilites. It shoots out the top of the head and rises high into the sky to form a purple cloud. It is not visible to the naked eye.

Only Chinese culture explains such things, but as to atmospheric phenomena that can be seen and what they foretell, the ancient Indian, Assyrian, Babylonian and Chinese all have books on this information, but if you have not opened a degree of wisdom the information is practically useless. Even if you know there will be an earthquake "soon", for instance, from a practical matter what can or should you do?
