Sometimes a planet becomes extremely negative in a horoscope and keeps on bothering and troubling the native more and more in spite of the native wearing Navagraha Mantrasthe gemstones for the positive planets and doing remedies for the negative planets. In such extreme cases, the Mantra for the extremely negative planet is prescribed. Chanting the Mantra of a particular planet for a specific number of times in a given time frame helps reducing the negative effects of the planet. And though I put a great deal of emphasis on gemstones and the magic done by gemstones, I would like to mention here that the Mantras are by all mean superior to gemstones and there is no doubt that they are the Supreme remedies available in astrology. There is no remedy in astrology like chanting of Mantras.
And one more good thing about them is that unlike gemstones, the Mantras only give positive effects and there are no negative effects for the Mantras, though there may be sometimes some minor side effects due to the excess of energy of some planet for which a person is chanting the Mantras. So in case you are chanting Mantras for a planet which is positive in your horoscope, the planet will start gaining strength as the Mantras will transmit the energy of the planet into your body in the same way the gemstones do, though the mechanism of gemstones and Mantras are different. And if you are chanting the Mantras for a planet which is extremely negative in your horoscope, the negative effect of the planet will start reducing as you keep on chanting the Mantra for that planet. So the Mantras can be used for both the positive and negative planets without any negative effects. But the use of Mantras is still very limited in astrology in spite of so many benefits and no negative effects.
