The fruit of holding the eight faced Rudrâksa seed has been said. Now I will talk of the nine-faced Rudrâksam. It is verily the Bhairava made manifest. On the left hand it should be worn. By this, the people get both Bhoga (enjoyment) and Moksa (liberation)
and they become powerful like Me and get themselves freed at once, without the least delay, of the sins incurred by committing thousands of abortions, hundreds of Brahmâhattyâs (killing the Brâhmanas). Holding the ten-faced Rudrâksa is verily wearing Janârdana, the Deva of the Devas. The holding of which pacifies the evils caused by planets, Pis'âchas, Vetâlas, Brahmâ Râksasas, and Pannagas. The eleven-faced Rudrâksam is like the Eleven Rudras. The fruits, the efficacy of which I now describe. Hear. The fruits obtained through the performance of one thousand horse sacrifices, one hundred Vâjapeya sacrifices, and making gifts of one hundred thousand cows are obtained thereby.
If one wears the twelve-headed Rudrâksam on one's ear, the Âdityas get satisfied. The fruits of performing Gomedha and As'vamedha sacrifices are obtained thereby. No fear comes from burned buffaloes, armed enemies and wolves and tigers and other murderous animals. Also the several diseases of the body never come to him. The holder of the twelve-faced Rudrâksa seed feels always happy and he is the master of some kingdoms He becomes freed of the sins incurred in killing elephants, horses, deer, cats, snakes, mice, frogs, asses, foxes and various other animals.
O Child! The thirteen faced Rudrâksam is very rare; if anybody gets it, he becomes like Kârti Keya and gets all desires fulfilled; and the eight siddhis are under his grasp. He learns how to make gold, silver and other metals; he attains all sorts of enjoyments. There is no manner of doubt in this. O Sadânana! If anybody holds the thirteen faced Rudrâksam, he becomes freed from the sins incurred in killing mother, father and brothers.
O Son! If one holds on one's head the fourteen faced Rudrâksam always, one becomes like S’iva. O Muni! What more shall I speak to you! The Devas pay their respects to one holding the fourteen faced Rudrâksas and he in the end attains the Highest Goal, the state of S’iva. His body becomes verily the body of S’iva.
