8 faced Rudraksha is an effective Rudraksha to diminish the effects of miseries due to the sins of the past. This Rudraksha is ruled by Lord Shiva's sons - Lord Ganesha and Kartikeya. Through this association, it leads to removal of obstacles and protects the wearer from people who unfairly create obstacles. Ganesha rules over planet Ketu and, hence, wearing this Rudraksha removes the malefics of planet Ketu.
Other associations are with 8 demi-Gods (asthavasus), the Ganges, and the 24 hours of the day (8 prahars of 3 hours each). Wearer is blessed with piety, wisdom, wealth and
happiness. This is a great Rudraksha to be worn by all.
