The nine grahas

What each of the nine grahas stands for, the signs it rules, where it is exalted and debilitated, and the day, colour, gemstone and mantra tradition gives it.

Navagraha

Sun to Ketu, one by one

Graha means “one who grasps”: each of the nine takes hold of a part of life. “Benefic” and “malefic” describe a graha’s natural temper, not good or bad luck. Every graha gives good results when it is well placed in a chart.
