Shastras say the two faced Rudraksha is an identity of Lord Ardhnarishwar. Two faced Rudraksha has two fissures on it. It cooperates to attain the peace of mind. The Ardhanarishwar form is a combination of male and female energy. It helps to seek reputation and harmony in married life and makes a balance between professional and personal life.
Note: We should grease Rudraksha using refined butter (Ghee) to prevent it from bursting.
