Etymology of Rudraksha
Rudraksha is termed by joining the 2 words - "Rudra" and "Aksha". ‘Rudra’ is one of the avatars of Lord Shiva and ‘Aksha’ means tears. The legend goes that the Shiva had to counteract powerful Demons in the ongoing war against gods.

Power of Rudraksha
Rudraksha carries within itself unique electro-magnetic properties, which in turn empowers the possessor when in touch with human body, or, even when it is safely kept in the house. Rudraksha enhances the effects of a weak planet, and streamlines the effects of a malefic one into a positive energy. Rudraksha is also known to produce heat, and can turn out to be allergic to skin in very rare cases. In such cases, a touch with the skin is not advised. Other than that, a rudraksha bead is completely harmless. Although it is advised that a competent astrologer should select a rudraksha after carefully going through ones horoscope, any selection of rudraksha bead do not harm the wearer in any case.
A rudraksha gives profound effects in the physical, mental and emotional enrichment of a person. It also empowers all to enhance their destinies and attain fulfilment in their lives. A rudraksha does not give its full effect till it has been purified and energized through rituals and puja. Any misuse of rudraksha can also cause loss of its powers. A strict precaution regime also has to be followed while wearing it. A proper Prana Pratishtha activates a rudraksha to give its immense blessings to the one wearing it.
