Saturn and Rahu are top grade malefic planets. Rahu signifies revolutionary mindset, illusions, hypnosis, hallucinations, awfulness, sudden incidence, unrecognized disease and it gives awareness. Whereas, Saturn may put you under financial and personal stress, create frequent obstacles and stop you from achieving success easily. Saturn will challenge you and if you do not rise up to the challenge then you may face failure.
