The
one 
mukhi rudraksha is blessed by Lord Shiva himself. One mukhi rudraksha washes away the sins as serious as 'brahma hatya' (killing of Brahmin). It enhances knowledge about the Supreme (Brahma Gyan) and the wearer is known to win over his senses. He then engages himself in Para-Tatva (Shiva Tatva). It is also known to give external bliss and nirvana (moksha) after death. At whichever place this rudraksha is worshiped, Goddess Lakshmi (Goddess of Wealth) bestows her presence. It is the most auspicious rudraksha among all beads and not only does it bring the wearer or worshiper closer to Shiva (spirituality and kindness) but also fulfills all his or her desires in the material world. The wearer also gains powers of concentration and enjoys inner peace.
As per Shiva Puran, one mukhi rudraksha offers worldly pleasures and salvation and therefore has a unique place among all the rudrakshas. It gives leadership qualities and skills to cope with stressful situations and hence is a preferred choice for those who assume leadership roles or head any organisation.
The controlling planet of this rudraksha is Sun. All negative effects posed by this planet on a person are got over by wearing this rudraksha. It's use is said to cure headache, eye defects, piles and diseases of the liver and skin.
All adult persons can wear this rudraksha. It can also be kept in a puja room or altar, where regular worshipping can be done. One mukhi in Chandrakar form is a symbolic rudraksha especially for invoking the blessings of Lord Shiva and hence it can be worn by all or kept in a puja room.
Chandrakar is an alternative for one mukhi rudraksha. A one mukhi bead is worn by persons requiring favour of Sun as a planet or to remove its malevolent effects, or those seeking devotion to God, minimising attachments to the wordly things and ultimately hoping to attain nirvana.
