The most loved Rudraksha to Lord Shiva is Rudraksha 14. This Rudraksha is not only considered in the form of Hanuman Ji, but it is also considered as a form of 14 Vidya, 14 lok and 14 Manu.
The 14 Mukhi Rudraksha is the most beneficial for removing Shani's defect. Apart from this, due to the form of Lord Hanuman, there is a special merit of Hanuman Ji on the person carrying this Rudraksha. It honours a man and rescues him from going to jail. It is so beneficial that Lord Shiv himself also used this Rudraksha.
