About Kalasarpa Yoga
Kalasarpa Yoga (the "serpent of time") occurs when all seven classical planets — Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn — are confined to one side of the Rahu–Ketu axis. There are 12 named types depending on the sign occupied by Rahu. It is said to bring delays, struggles and sudden ups and downs, but also intense focus and the potential for remarkable achievement once the karma is worked through. If even one planet falls outside the axis, the yoga is considered partial or absent.
