Lord Shiva has three eyes. One special eye of power at his anga Chakra. Rudra eyes are compared with rudraksha. Rudraksha word if gramatically divided then it becomes Rudraksha = rudra + aksha. Rudra = Lord Shiva himselft. Aksha = eyes. So Rudraksha is equally compared with the eyes of lord shiva.
How rudaksha came into existance
There are epic history stories on the birth of rudaksha . It is believed that Mahadev once made meditation for very long time. He sat on his asana for years together doing his meditation and Tapasya. His long austerity was for the betterness of the whole society or mankind. After long time he felt much satisfaction and joy. He was happy and content. He opened his netra or eyes to see the happy world. He was happy and his eyes was full of water after seeing goodness in the world. The water or tear from his eyes fell down the earth. Whereever it fell, there his powers of austerity grown as tree and the fruit was rudraksha. The beads of the rudraksha tree was so powerful that it was soon used by people for getting blessings of the lord. Hence the rudraksha tree was born.
