Just as each Rudraksha has affinity to a particular deity and planet, it also has a specific mantra. Before wearing the rudraksha, one must wash it in panchamruta (mixture of water, milk, curd, ghee and honey), perform Shiva Pooja and then recite the specific mantra 108 times. The Pooja can be performed on any Monday, or the particular day of the concerned planet or deity, or any special auspicious days – like Navaratris, Deepavali etc.
The following are the mantras for the various mukhi Rudrakshas.
