According to ancient texts, Rudraksha are very influential in removing malefic effects of the planets. Gems are used specially for enhancing the strong  planets . But they are unable to pacify the evil influence hence it is most advisable to wear Rudraksha. Then not only planets are pacified but peace, harmony, good health and abundance comes to its wearer and he becomes a favorite of Lord Shiva. Therefore a man must know which Rudraksha will be useful to him.
