Rudraksha have been worn since times immemorial due to properties of the specific beads of different facets. They have no negative effects of any kind and are not dependent on planets the way gems are. Modern astrologers consider that rudraksha pacify planets .
There is NO wrong combination, and No side effect of any kind, so one needs to go ahead and select his own rudraksha. These facts can be verified by reading our ancients texts that state that all rudraksha may be worn by all irrespective of caste, sex and religion.
