The most special Rudraksha
We see a lot of rudrakshas offering on the shivalingam. And the symbol of Rudraksha the tears of lord Shiva. If we try to understand the true meaning of this then we feel it means "to get the highest consciousness". In Shivapurana it is said "Whoever wears rudrakshas on both hands, on the head - no materialistic weapon can kill. Non-Materials can not harm the physical body.". Mostly yogis around Himalayas always wear many numbers of Rudraksha beads. As it is protective so they wear it on the hands and also on the head.
We have various kinds of Rudraksha. It starts from one-face or ek-mukha of Rudraksha also known as the king of Rudraksha. As the name suggests, it is truly the king of all the rudrakshas. We have two-face or do-face which is representing both Shiva and Shakti, the Rudraksha meant for couple or relationship. Brahma, Vishnu and Maheswara are combined represented by three-face or teen-mukha Rudraksha. And so the Rudraksha types goes on. Shivapurana describes that "There exists totally 27 kinds of Rudraksha beads".
According to the holy Shivapurana, the top most special rudraksha is the twenty-seven-face or shataish-mukha Rudraksha. It is noted in history to have appeared only one time during Lord Rama's time. Shiva had given 27 mukhi bead to Ravana as he wanted to have immortality and desire fulfillment. When Lord Rama killed Ravana, the 27 faced bead slipped deep inside the earth. And no one was able to see that from there.
