Rahu is by nature a malevolent planetary influence which can cause personal frustration, sacrileges habits, abuse of alcohol and drugs, possession of ghosts and demons, and infectious diseases. However, when located in a powerful spot in one's horoscope, Rahu can elevate one to positions of great wealth and power and confer public influence over the masses. Rahu is associated with serpents, fear, karmic retribution, and un-virtuous characters.

Persons with Rahu exalted are wealthy and fortunate. But those who have a weak or afflicted Rahu in their horoscope have a tendency to suffer from fear of supernatural phenomena and suicidal impulses. ULTRA-VIOLET is the cosmic color transmitted by hessonite and other orange gems. Ultra-violet color waves are the coldest of all the cosmic rays and should only be used for ailments caused by extreme over-heating, i.e., high fever, hyper-acidity, indigestion, hyper-sexuality, insomnia, and during child birth. Rahu astral talismans may also help divert disasters, prevent insanity, counteract poisons, and protect one from demoniac influences. Rahu is particularly associated with scientific genius and the ability to deal successfully with people of lower status, such as servants, employees, and underworld characters.

Gemstones governed by Rahu include hessonite, spessertite, zircon (hyacinth), and other natural gems of golden-orange to brownish-orange hues. Only flawless (eye-clean) stones transmit beneficial Rahu energy.
