I have described eight kinds of Ganesha idols, which are made using different materials and what is believed to be gained from the worship of these Murtis.
For getting prosperity in trade and business- Sandalwood [Chandana]
For getting fame, success and popularity- Silver [Chandi]
For Santan Prapti or gaining progeny- Copper [Tamba]
For freedom from chronic diseases-Gold [Sona]
For matters related to land and property-Stone [Patthar]
For political success or gaining social power- Red Coral [Moonga]
For trouble free and long life- Sandalwood or Wood [Chandana or Lakdi]
For enemy problems and triumph over enemies- Clay or Wood- [Mitti or Lakdi]
If unable to afford purchasing a special Ganesh Murti, due to money constraints, wearing a small locket or ring of Ganesha is also believed to be helpful in resolving the specific problems. Ganesh Bhakts can also see the section on Ganesha Mantras for resolving their problems.
For seekers of the spiritual bliss and freedom from the unending life cycle of birth and death visualizing a Blue Colored Ganesha, while in meditation is believed to be helpful in getting success in their quest.
