Gardhabha yoga: Gardhabha means donkey. It is a bad yoga. It occurs if in the Navamamsa chart if Saturn is placed in the 10th house from the navamamsa lagna.
Results: One will work like a donkey (very had work) and others will enjoy the fruits of his hard work.
This is not in the 300 important yogas by B.V.Raman but was told to me by the legendary astrologer P.S.Iyer.
