In Hindu mythology, the two demons Rahu and Ketu are said to "swallow" the sun during eclipses, snuffing out its life-giving light and causing food to become inedible and water undrinkable.
Pregnant women are advised to stay indoors to prevent their babies developing birth defects, while prayers, fasting and ritual bathing, particularly in holy rivers, are encouraged.
The problem with this is that, when something like this is mentioned, then any incident of any kind, whether big or small, will be used to justify the accuracy of such a prediction. This is because when you make a prediction that is VAGUE enough, something that science can't get away with to be considered to be valid, then you have enough of a wiggle room to fit anything in it. You are also inviting some crazy nut to actually commit something on that day simply to fulfill the prophecy.
Still, I want to see evidence that food becomes inedible and water undrinkable during the eclipse. If this is false, then someone needs to being these astrologers to task for the lies. But, that's not going to happen, is it?
