What are the positive aspects? How a Rudraksha changes one's life?

How it works is Rudraksha is, like I said, beed manifested byiva for the healing of mankind. Each of the faces of the Rudraksha will carry a certain energy. For example, a 14-Mukhi Rudraksha will be of Shani, Mahashan Rudraksha. It's known as Saturn. If a person's Saturn is weak and they wear the 14-Mukhi Rudraksha, the debilitation can change into an exaltation. It will increase the power of the planet and hence show positive impact to the well. The transformation that I have seen cannot be described with words. That's how powerful a Rudraksha.
