5 Mukhi Rudraksha as found in various Puranas :
5 Mukhi Rudraksha is the form of Rudra named Kaalagni. The wealth, in the form of learning that a man gains in the world, should be apparent and permanent only then it is meaningful. Five faced Rudraksha is useful for this purpose. In the long run we lose our power to maintain the learning that we have gained and at last it vanishes. We forget the acquired learning or cannot remember the lost learning only after wearing the five faced Rudraksha. Agni ( fire ) purifies the metals and similarly five faced Rudraksha rectifies all the vices and faults of Jeeva and makes him pure and Jeeva gains the form of Pashupati i.e. the Lord of all creatures after becoming free from the animal instincts.
A mala of five face Rudraksha is also worn. By wearing a 5 Faced Rudraksha mala the wearer’s mind remains peaceful. There is no suspicion about the fact that the wearer of Five faced Rudraksha mala never gets untimely death. It keeps the blood pressure normal and the fear of untimely death disappears. If three beads of Five faced Rudraksha are dipped overnight in water in a glass / Copper vessel and by drinking the water in the morning on empty stomach, the person gets free from blood pressure and related illnesses.
