Power of Ganesh Rudraksha
If a Rudraksha of any mukh gets a protrusion on its body similar to trunk of any elephant, this rudraksha is called a Ganesh Rudraksha. Only in recent times this rudraksha has received wide popularity. The bead resembles Lord Ganesha with his trunk. In view of high prices commanded by eight or 11 mukhi rudraksha, which are also blessed by Ganesh, traders sell this rudraksha as a cheaper alternative.
Ganesh rudraksha is used alternatively with other beads in a Siddha Mala to make up for the numbers to 27 (1 to 14 mukhi beads will require 13 Ganesh rudraksha). Thirty two beads of Ganesh rudraksha are strung together to make a Kantha, which people keep at worshipping place to protect them and to remove any obstacles in life. Some people even wear such a Kantha regularly.
Some people get obsessed with the image of Ganash in rudraksha to such an extent that they look for the contours on the surface of any rudraksha resembling Lord Ganesh. There are books written on this issue and the whole approach looks intriguing and questionable. Practically, only such rudraksha is called Ganesh rudraksha, which has a trunk-like elevation on its body.
In addition to the above varieties, there are possibilities of getting several other varieties since it is a product of nature. For example, Sawar, which is a Gaurishankar rudraksha with one bead having only one line and another bead a normal rudraksha of four to seven mukhs. Then there is Nandi rudraksha, which has two trunk-like protrusions on two sides of the bead. Some call this bead Dwi Ganesh.
All these varieties and others not explained and available from nature are revered by people who use then in the hope of deriving benefits. No authentic information is available about specific properties of these beads. If one wishes to use such rudraksha, it should be done with full devotion and the wearing procedure shall be the same like other rudraksha and mantra of Om Namah Shivaya should be chanted.
