Ketu is a mysterious planetary influence which, like Rahu, is malevolent and afflictive unless located in a powerful position or conjoined with beneficent planet. Ketu governs theology, monastic life, crime and punishment, hidden enemies and dangers, and the occult. Unless correctly balanced, ketu can cause poverty and other obstructions in one's life. Ketu is associated with suffering and the consequent aspiration for spiritual liberation.
If ketu is exalted, one will be wealthy and protected from evil. But if Ketu appears in a weak or harmful position in one's horoscope, one becomes prone to fatal diseases of a mysterious nature as well as compulsive gambling.
