15 Mukhi Rudraksha is very dear to Lord Shiva because it is the symbol of Lord Pashupati Nath and he himself is a form of Lord Shiva. In the name of Lord Pashupati Nath, a Grand Temple in the form of Divya Peeth was established in Nepal. The term Rudraksha (Rudra i.e. Shiva + aksha i.e. eye) stands for the eyes of Lord Shiva or Rudra implying thereby that it was pleasant to the eyes of Lord Shiva, and hence named in His Honour. The mantra to wear this bead is “OM NAMAH” but to get the best results, one should enchant the “Mrityunjay Mantra” after wearing it.
