1) It is an evergreen broad-leaved tree whose seeds is used in India, Nepal and other Asian countries for making rosary (rudraksha japa-mala);
2) A rosary for japa (reading of mantras). Use of rosary has particular meaning and importance. Rosaries from seeds of rudraksha are mainly used for japa. Usually Saivas wear rudraksha-mala around the neck, on the arms or in the special pouch. The number of beads in chain is 108 mostly, but also there are malas with less number of beads (for example, 54 or 18). Beads needed for counting the number of read mantras. Seeds of rudraksha are important for yogis for different reasons. The word “rudraksha” means “Rudra’s (Shiva’s) eyes” and represents the third eye of transcendental vision. The seeds of rudraksha have specific grooves or “faces”. A common type has five divisions, and these are symbolic of the five faces (“mukhas”) of Shiva. It is considered the chain of 108 beads represents the sequence of numerous Siva’s manifestations on the Earth. Some seeds of rudraksha may have above forteen “faces”. The “Chandrajnana agama” describes results of wearing rudrakshas depending on number of its faces. Seeds of rudraksha are also used in some pujas.
In some cases for tantric mantras are used malas of others materials (stone or coral, for example). Following mantra for rudraksha is reading when you are wearing the mala at the beginning of the day. This mantra is also used for purification of the rosary.
