Malefic and malevolent forces do not disturb the person, if he is wearing a 10 Mukhi Rudraksha. Thus he can focus on his spiritual practices, unhindered.

Shrimad Devi Bhagavatam Chapter. 4, Shloka. 23

Essence of Ten Mukhi Rudraksha:

Wearing the 10 Mukhi Rudraksha is the closest you can get to Lord Vishnu and experience his protection in day to day life.

As per our scriptures, 10 Mukhi Rudraksha is effective for cleansing and balancing all the Chakras. Malefic and malevolent forces do not disturb the person if he is wearing a Ten Mukhi bead. Thus he can focus on his spiritual practices, unhindered.

The 10 Mukhi Rudraksha is blessed by Lord Vishnu. The Hindu Trinity consists of Brahma, Vishnu and Mahesh. Here Vishnu (Narayana / Krishna) is in charge of protection and sustenance of all living beings in the universe. Lord Vishnu takes ten Avatars in each of the Maha Yuga after a Pralaya and therefore the 10 Mukhi represents the Dasa Avatars of Lord Vishnu. Lord Shiva himself assigned the 10 Mukhi Rudraksha to Narayana Krishna. The Shrimad Devi Bhagwatam and Mantra Maharnava mention this. However the Rudraksha Jabalo Upanishad mentions that this bead is blessed by Yamraaj (the God of death) and the guardians of the 10 directions (10 Dikpals).
