There is kind of Rudraksha which bears Trunk like elevation as is seen on the face of Lord Ganesha, the son of Lord Shiva. It is called Ganesh Rudraksha. It provides the wearer perfection in every sphere in life and the grace of Lord Ganesha is received by him. The Ganesh Rudraksha Bead is really special due to the way it grows the thorny protrusions of the outer surface of the Bead.
Mantra for the Ganesh Rudraksha bead can be any of the beautiful Lord Ganesh Rudraksha Mantras found in the book Healing Mantras by Thomas Ashley–Farrand like "Om Gam Ganpatayay Namoh Namah", "Om Ganeshaya Namah".
The Ganesh Rudraksha can be kept at the place of worship and should be daily worshipped to gain the blessings of "Riddhi-Siddhi Dayak" Sri Lord Ganesha.
A man who wears a garland including beads of Rudraksha from one to fourteen faces and the rest five faced Rudraksha which count hundred eight beads in all, is a god incarnate himself. According to Puranas if a man wears Rudraksha in definite number at special points on the body, he becomes like Lord Shiva himself.
