There were many other fall outs – astrologically. Sun and Moon, the snitches, became Swarbhanu’s hated enemies. The names were changed – the head was called Rahu and the tail Ketu. Rahu swallows the luminaries on particular stellar configurations (the eclipse) but since it has no body, the Sun and the Moon soon emerge through the hole in the neck. Thank God!
It is debatable whether kaal–Sarp is an unmitigated evil. Many great men had this Yoga in their horoscopes. Some have been Presidents and Prime Ministers and others have been conquerors. It is said that Genghis Khan had it. One thing is clear. With kaal–Sarp, you may climb very high. But one day there will be a downfall. And the higher you climb, the harder you fall.
