Jupiter, Venus, Moon, Mercury are considered as Benefic Planets. Jupiter promotes wealth, happiness, wisdom and long term health, Venus on the other hand does not give as enduring and long term results as Jupiter, it gives sense of creativity, happiness, good health for a short tenure. The moon if located close to the sun may become malefic, however it’s usually benefic. Mercury is a weak planet and tends to take on the influence of bad or malefic planets but it promotes positive and harmonious thoughts, actions and expressions. If these planets have Vata Dosha which brings upon the forces of deterioration, then their malefic impact is nullified and they cause diseases having long term effects.
