Rudr+aksha meaning—the eye of Lord Rudra [Shiva] is considered to be the most potent manifestation of the Cosmic Force. Hence Rudraksha is the object of veneration and also the source to reach the higher self. Rudraksha is often believed to symbolize the link between the earth and the heaven. These beads are the seeds of the Rudraksha fruit obtained from Rudraksha trees. The Rudraksha tree is botanically known as Elaeocarpus Ganitrus ROXB. Its English name is Utrasum bead tree.
There are clefts called Mukhis on the surface of the beads. The number of Mukhis on the surface of a Rudraksha bead helps in determining its quality. According to the number of Mukhis the Rudraksha bead ranges from single face to a several faced bead. Asians have used Rudraksha beads traditionally. Asian Yogis and Monks found that merely wearing the Rudraksha beads gave them astonishingly tremendous amount of tranquility, concentration that helped them meditate for a long period of time with spectacular control over their mind.
Here are some pictures of the beads and the tree we saw there.
