Rahu, the north node, is equated with Saturn, the great malefic by Vedic Astrologers. A strong Rahu gives the individual worldly powers and success. In the spiritual realm, Rahu can give psychic powers, but also there may be danger from drugs and black magic. On the positive side, the influence of Rahu can put us in harmony with collective trends and give popularity, prestige, fame, and power. The power of Mantras & Shlokas has been acknowledged since time immemorial. A Mantra can consist of a powerful word or a combination of words and can be used for self-realization, for freedom from worries, to fulfill one's desires, to ward off the effects of malefic planets, to bring you success, peace, and contentment—the range is truly vast. You can choose for yourself.

Gayatri Mantra for Rahu

"Om Sookdantaya vidmahe, Ugraroopaya dhimahi, tanno Rahu prachodayat"

This Gayatri mantra consists of three parts. The first is the chants to Rahu. The second is the mantra proper. The third is a summary of the mantra's energies.

The Gayatri mantra is chanted at sunrise, noon, and sunset. At dawn, it is called Gayatri, the youthful form of the Goddess, consort of Lord Brahma, the creator. It is called Savitri, the mature form, at noon, the consort of Lord Shiva. It is called Sarasvati, the elderly form, at sunset, the consort of Lord Vishnu.

Puranic Mantra for Propitiating Rahu

You may also opt to chant the following puranic mantra for propitiating Rahu (18,000 times):

Ardha-kayam mahim-viryam chandraditya-vimardanam
simhika-garbha-sambhutam tam rahum pranamamy aham

When translated into English, it means: "I offer my obeisances to Rahu, born from the womb of Simhika, who has only half a body yet possesses great power, being able to subdue the Sun and the Moon."

Mantras must be chanted or recited with unwavering devotion and motivation. Chanting them as a matter-of-course deprives them of power and is practically useless from the point of view of conscious growth, evolution, and effect.
