The best Rudraksha for attaining business success is the 21 face Rudraksha. It is widely believed that those wearing the 21 Mukhi Rudraksh will be able to achieve huge profit in business through the blessing of Kuber and Goddess Lakshmi.
7-face Rudraksha is also associated with money making. The 7 mukhi is believed to have the blessing of Goddess Lakshmi.
6-face Rudraksha is also worn for gaining money as it is associated with Shukra Grah.
It must be noted here that there is no single opinion in this matter. Astrologer and Rudraksh experts give different opinions.
The best solution is to wear the Rudraksha that you have in your possession and be devoted, hard working and determined. Shiva is present in all forms of Rudraksh. So what matters in the end is your devotion.
