The three mukhi wearer does not come to a womb again (does not take birth), does not suffer from any disease and does not lead an indisciplined life. He is never defeated (his/her) house never catches fire get destroyed. All the above and beyond any and above all difficulties get resolved by three mukhi rudraksha.
