Adiyogi Pendant (11 Mukhi Nepali Rudraksha)

The Padma Purana account (via Kanchi Kamakoti Peetham) links the eleven-faced bead to the Ekadasha Rudras (the eleven forms of Rudra/Shiva) or, alternatively, to Hanuman, with the mantra Om Shri Rudraya Namah. Wikipedia's summary of rudraksha customs separately notes that the eleven-faced bead is traditionally worn by renunciants. Shiva is one of the principal deities of Hinduism. Described here as tradition, not as a guaranteed effect.

Seed of the Elaeocarpus ganitrus tree, worn as a prayer bead across Hindu and Buddhist tradition. Natural beads vary in colour and grain and may deepen with wear — a mark of a real bead, not a fault.

The pendant form's conceptual template is old: medieval reliquary pendants were made to hold fragments of saints' relics, establishing the idea of a precious, meaningful object worn close to the body at chest level. By the 16th century, portrait miniatures migrated into jewelry as secular pendant lockets, and by the Victorian era pendants and lockets had become a primary vehicle for sentiment, memory, and mourning in the West. Open to any devotee regardless of age or gender; choice of deity or symbol is generally personal (Ishta Devata) rather than restricted by tradition.

Keep away from water, perfume and harsh chemicals. Wipe gently with a soft, dry cloth and store flat, away from direct sunlight. Rudraksha and other natural beads may deepen in tone with wear — this is expected, and part of how a piece becomes yours.
