Rudraksha beads are seeds from the Rudraksha tree, which is found mainly in Indonesia, Nepal, and India. They are considered sacred in Hinduism and are believed to have spiritual and healing properties. The word "Rudraksha" is derived from the Sanskrit words "Rudra," which means Lord Shiva, and "Aksha," which means eye. Hence, Rudraksha beads are also called "the tears of Lord Shiva."
