The Rudraksha - the eyes of Rudra - the #LordShiva

Rudraksha is a Sanskrit compound word consisting of Rudra (Sanskrit: रुद्र) and akṣa (Sanskrit: अक्ष).

Rudra is one of Shiva's Vedic names

Sanskrit dictionaries translate akṣa (Sanskrit: अक्ष) as eyes, as do many prominent Hindus such as Sivaya Subramuniyaswami and Kamal Narayan Seetha; accordingly, rudraksha may be interpreted as meaning 

"eyes of Rudra"

Rudraksha tree, Elaeocarpus ganitrus

Of the 300 species of Elaeocarpus, 35 are found in India. The principal species of this genus is Elaeocarpus ganitrus, which has the common name of "rudraksha tree", and is found from the Gangetic plain in the foothills of the Himalayas to Nepal, South and Southeast Asia, parts of Australia, Guam, and Hawaii.

Rudraksha trees grow to 60–80 ft. They are evergreen trees that grow quickly, and as they mature their roots form buttresses, rising up near the trunk and radiating out along the surface of the ground.

Types of rudraksha stones

5-faced (pañcamukhi) rudraksha stone with the lines delineating its faces labeled 

Rudraksha stones are described as having a number of facets or "faces" (mukhi) that are separated by a line or cleft along the stone. Stones typically have between 1 and 21 faces, although most have between 4 and 6 faces. Those with a single face are the rarest. Rudrakshas from Nepal is between 20 and 35 mm (0.79 and 1.38 in) and those from Indonesia are between 5 and 25 mm (0.20 and 0.98 in). Rudraksha stones are most often brown, although white, red, yellow, or black stones may also be found.

Many types of stone are described. Gauri Shankar are two stones that are naturally conjoined. Sawar are gauri shankar in which one of the conjoined stones has just one face. Ganesha is stones that have a trunk-like protrusion on their bodies. Trijuti are three stones which are naturally conjoined. Other rare types include veda (4 conjoined sawars) and dwaita (2 conjoined sawars).

Rudraksha stones may be strung together as beads on a garland (mala) which can be worn around the neck. The beads are commonly strung on silk, or on a black or red cotton thread. Less often, jewelers use copper, silver, or gold wires. The rudraksha beads may be damaged if strung too tightly. The Devi-Bhagavata Purana describes the preparation of rudraksha garlands.

Several late-medieval Upanishads describe the construction, wearing, and use of rudraksha garlands as well as their mythological origin as the tears of Rudra.

तं गुहः प्रत्युवाच प्रवालमौक्तिकस्फटिकशङ्ख रजताष्टापदचन्दनपुत्रजीविकाब्जे रुद्राक्षा इति । आदिक्षान्तमूर्तिः सावधानभावा । सौवर्णं राजतं ताम्रं तन्मुखे मुखं तत्पुच्छे पुच्छं तदन्तरावर्तनक्रमेण योजयेत्

Sage Guha replied: (It is made of any one of the following 10 materials) Coral, Pearl, Crystal, Conch, Silver, Gold, Sandal, Putra-Jivika, Lotus, or Rudraksha. Each head must be devoted and thought of as presided over by the deities of Akara to Kshakara. The golden thread should bind the beads through the holes. On its right silver (caps) and left copper. The face of a bead should face, the face of another head and tail, the tail. Thus a circular formation must be made.

— Akshamalika Upanishad

अथ कालाग्निरुद्रं भगवन्तं सनत्कुमारः पप्रच्छाधीहि भगवन्रुद्राक्षधारणविधिं स होवाच रुद्रस्य नयनादुत्पन्ना रुद्राक्षा इति लोके ख्यायन्ते सदाशिवः संहारकाले संहारं कृत्वा संहाराक्षं मुकुलीकरोति तन्नयनाज्जाता रुद्राक्षा इति होवाच तस्माद्रुद्राक्षत्वमिति तद्रुद्राक्षे वाग्विषये कृते दशगोप्रदानेन यत्फलमवाप्नोति तत्फलमश्नुते स एष भस्मज्योती रुद्राक्ष इति तद्रुद्राक्षं करेण स्पृष्ट्वा धारणमात्रेण द्विसहस्रगोप्रदानफलं भवति । तद्रुद्राक्षे एकादशरुद्रत्वं च गच्छति । तद्रुद्राक्षे शिरसि धार्यमाणे कोटिगोप्रदानफलं भवति

Sage Sanatkumara approached Lord Kalagni Rudra and asked him, "Lord, kindly explain to me the method of wearing Rudraksha."

What he told him was, "Rudraksha became famous by that name because initially, it was produced from the eyes of Rudra. During the time of destruction and after the act of destruction, when Rudra closed his eye of destruction, Rudraksha was produced from that eye. That is the Rudraksha property of Rudraksha. 

Just by touching and wearing this Rudraksha, one gets the same effect of giving in charity one thousand cows."

— Brihajjabala Upanishad

तुलसीपारिजातश्रीवृक्षमूलादिकस्थले । पद्माक्षतुलसीकाष्ठरुद्राक्षकृतमालया

He should count using a rosary (mala) whose beads are either made of the tulsi plant or rudraksha.

— Rama Rahasya Upanishad

हृदयं कुण्डली भस्मरुद्राक्षगणदर्शनम् । तारसारं महावाक्यं पञ्चब्रह्माग्निहोत्रकम्

After prostrating himself before the celebrated form of Sri Mahadeva-Rudra in his heart, adoring the sacred Bhasma and Rudraksha and mentally reciting the great Mahavakya-Mantra, Tarasara, Sage Shuka asked his father Geat Sage Vyasa.

— Rudrahridaya Upanishad

अथ हैनं कालाग्निरुद्रं भुसुण्डः पप्रच्छ कथं रुद्राक्षोत्पत्तिः । तद्धारणात्किं फलमिति । तं होवाच भगवान्कालाग्निरुद्रः । त्रिपुरवधार्थमहं निमीलिताक्षोऽभवम् ।निमीलिताक्षोऽभवम् तेभ्यो जलबिन्दवो भूमौ पतितास्ते रुद्राक्षा जाताः ।  सर्वानुग्रहार्थाय तेषां नामोच्चारणमात्रेण दशगोप्रदानफलं दर्शनस्पर्शनाभ्यां द्विगुणं फलमत ऊर्ध्वं वक्तुं न शक्नोमि

Sage Bhusunda questioned Lord Kalagni-Rudra: 

What is the beginning of Rudraksha beads? 

What is the benefit of wearing them on the body? 

Lord Kalagni-Rudra answered him thus: 

I closed my eyes for the sake of destroying Tripurasura. From my eyes thus closed, drops of water fell on the earth. These drops of tears turned into Rudrakshas. By the mere utterance of the name of 'Rudraksha', one acquires the benefit of giving ten cows in charity. By seeing and touching it, one attains double that benefit. I am unable to praise it anymore.
