We have mostly seen Shiva wearing the rudraksha, but we are unaware of origin of Rudraksha or benefits of wearing rudraksha.
Word Rudraksha is derived from 2 words: Rudra and Aksha. Rudra is another name for Shiva, and Aksha means tear drops. Once Rudra was performing penance for thousands of years and Rudra’s mind was in flutter. For desire to help the world, when Rudra opened his eyes after performing penance for thousands of years, drops of tears fell from Rudra’s eyes. From these tears, there grow giant Rudraksha’s tree. After that Rudrakshas were grown in different part of the world.
In order to bless the devotees; Rudraksha was given to four different castes (varna); white Rudrakshas were given to Brahmin, red Rudrakshas were given to Kshatriya; yellow Rudrakshas were given to Vaishya and black Rudrakshas were given to sudra.
Different sizes of Rudrakshas has different benefits; Rudrakshas have been worn and used for meditation, japa mantra, and pujas/fire ceremonies for many centuries. Asian Yogis and Monks found that merely wearing the Rudraksha beads gave them astonishingly tremendous amount of tranquility, concentration that helped them meditate for a long period of time with spectacular control over their mind. Buddha wore Rudraksha beads, along with the Dalai Lama, Gandhi, and many enlightened Indian yogis.
Rudrakshas in the size of jujube brings tons of happiness and good fortune. Rudrakshas in the size of berry is conducive to the achievement of all desires. Lighter the Rudrakshas, the more fruitful it is.
Medicinally they are known to: heal many of the mind & body ailments, be cooling when worn against the skin, reduce heart disease and lower blood pressure, increase mental clarity, memory & general awareness, calm the central nervous system, quiet the mind & free one from negative thoughts, increase immunity, energy & stamina, and rejuvenate the entire mind & body.
Why Wear it?
The wearing of the Rudraksha is recommended for the sake of destroying sins. Devotees wearing Rudraksha shall refrain from eating onion, garlic, meat and liquors. The individual who wears the Rudraksha with devotion is like Rudra himself. If man with devotion drinks then Rudra drinks. One who feels shame in wearing this divine Rudraksha can never be free from cycle of death and birth even after taking millions of birth. Person who criticizes Rudraksha wearer is sinner. No pleasure is greater in this world then wearing the Rudraksha.
