In Vedic Astrology, Rahu represents obsession, attachment, distorted perception, blowing things out of proportion, psychic ability.
In Vedic Astrology, Rahu is considered a malefic planet by nature. It doesn’t rule any sign. Its opposing side is Ketu. It is considered the body of the serpent. It represents attachment, compulsiveness, fame, worldly pursuits, and material wealth.
We only recommend strengthening Rahu with a hessonite (gomed) if one wishes to strengthen the effects of Rahu in their lives. This can promote fame and protection if one is on the right track. Otherwise we recommend appeasing Rahu with the upayas (remedies) mentioned below, and strengthening your most auspicious planets with gems first and foremost.
