Rudrakshas are believed to be the seeds of the Rudraksha tree, which is said to have originated from the tears of Lord Shiva. The beads are considered sacred because they are believed to carry the vibrational energy of the divine. In Hindu mythology, Rudrakshas are associated with the destruction of evil and the protection of good. Wearing Rudraksha beads is believed to bring spiritual growth, peace, and prosperity to the wearer.
