Navgraha Shanti Kavach
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).
The 11 Mukhi Rudraksha is blessed by Lord Hanuman. He is also called as Ekadash Rudra. Hanuman is virtuous, strong and infallible in his physical, mental and oratorical skills. As per the Padma Purana anyone who wears the 11 Mukhi is known to be abundantly blessed with all the virtues of Lord Hanuman. He would gain negotiation skills, self-confidence, intelligence, physical strength and a powerful mind.
This divine bead has a unique power to control the physical senses. It is believed makes the wearer fearless and is highly recommend during meditation and also to inculcate single minded devotion to God. Lord Indra also blesses this Rudraksha. This bead brings good luck, good fortune, man-management skills and power to gain absolute control over senses. The eleven Rudras reside in the 11 facets of this bead. The Hanuman Chalisa sums up the energy of Lord Hanuman in some simple stanzas.
Even merely meditating on Lord Hanuman is said to boost strength, self-confidence and courage. This is the true essence of the divine energy that rules the 11 Mukhi Rudraksha. This bead controls the malefic effects of the planet Mars. It is worn individually around the neck. Ancient scriptures advised people to wear it on the Shikha (tuft of hair on top of the head) to energize the Sahasrara / Crown Chakra. It is also worn with the 9 and 10 Mukhi Rudraksha in the power combination for protection.
