Lotus Seed beads are dried seeds from plants of the genus Nelumbo. Lotus Seeds are important in many parts of Asia and the Indian subcontinent in everything from religion to medicine to food. The Lotus Flower has great significance in Tibetan Buddhism. Many deities are depicted seated upon lotus flowers, or in some cases such as Padmasambhava (The Lotus Born), having arisen from the Lotus Flower.
Tibetan Buddhist malas have 108 beads, a cosmic number. It's 3 X 36 and 4 X 27. We have heard that with earnest devotion the practitioner can charge each bead with spiritual energy. Some beads are more effective at holding a charge. Pearls, lapis, amethyst, quartz, lotus seeds and bodhi seeds are a few that come to mind.
