RAHU Problems----- http://www.astrologyguild.com/remidial.htm
Many individuals are quire unaware about how damaging Rahu periods or transits have the potential to be. Rahu can cause intense dissatisfaction with life, and in its transit over any angle, can cause intense dissatisfaction or unhappiness. Rahu or Ketu can cause susceptibility to gossip, black magic, sudden bursts of anger, jealousy, poisons and disease. It can also generate affliction from psychic forces and ghosts. Happily, although Rahu can cause intense problems, it is also quite amenable to relatively simple solutions.
Any kind of protective items, such as Feng Shui mirrors, witches balls (these are blown glass spheres which are supposed to capture negative energy in them); Drishti yantras and other "protective items" are extremely effective against the afflictions caused by the nodes.
I will share one extremely effective technique which I was taught by a South Indian Priest (Sathashivam Sivacharya) for dealing with back luck, which is usually the domain of Rahu:
Take some brandy (no particular quality is recommended. Place it in a glass bottle with uncooked rice (something like a relish jar is appropriate.). Bring the jar to a four corners at mid night on a new moon evening. Smash the jar and turn around and walk away. DO NOT LOOK BEHIND YOU WHEN YOU WALK AWAY. This dissipates bad luck and keeps malicious gossip away. The brandy will and rice being broken attracts demonic energies when they are most powerful, but the broken glass damages them for a full month. Keep in mind that when the Moon is at its darkest is the time when these energies are most present. Smashing the bottle leaves the bad patterns behind and damaged. Looking back just encourages them to return to your life. This technique works very well.
Here is a special mantra for Rahu from Shiv Raja Sharma's text, The Mystery of Rahu in a Horoscope (p. 3, 1995, Sagar Publications), which I have found very powerful in encouraging Rahu's more positive qualities:
Rahurdnava Mantri Cha Simhikachittananda
Ardhakaya Sada Krodhi Chandradity Vimardana
Giver of happiness to Simika (his mother), minister of demons,
half-bodied, Rahu is the tormenter of the Sun and the Moon
Roudro Rudrapriyo Daitya Swarbhanurbhanur Bheetidah
Graharajah Sudhapayi Rakatishyabhilashuka
Terrible looking, devotee of Lord Shiva, king among planets, immortal because he has drunk nectar, Rahu who frightens the Sun feels happy when he is worshipped at night.
Kaaldrishti Kaalroopa Shri Kantha Hriyadasraayah
Vidhuntudah Saimhikayo Ghorarupo Mahabalah
His sight is death inflicting; his looks are Death-like; he resides in the heart of Lord Neelakantha: has made the Moon lusterless. The son of Simhika is powerful.
Grahapeedikaro Dranshtri Rakta netro madodarah
Panchavimsati Namaani Smritava Rahum Sadanarah
He who torments planets has blood red eyes, big bellied (hard to satisfy): these are the twenty five names of Rahu.
Yah Pathet Mahati Peeda Tasya Nashyati Kevalam
Arogyam Putramtulam Shriyam Dhanyam Pashumtata
He who recites these names overcomes his troubles by a mere recitation of these names, gets sons, good health, prosperity, agriculture and cattle wealth.
Dadati Rahustasmai Yah Pathet Stotram Utttamam
Satatam Pathet Yastu Jeevat Varsham Shatam Narah
He who recites this stotra constantly gets his wishes fulfilled and lives up to the age of one hundred years. That is the fruit of reciting this hymn.
