I read one online article on power of rudraksha. It can be followed /rudrakshapower1
All beads have some power within them. And each are differentiated by their special powers. Each rudraksha bead need to be either worn as single or be worn as a mala.
Power of the beads are felt within few days of wearing. Say it may be maximum 2-3 days within which the wearer feels a super natural positive power within himself and also feels relaxed and happy.
