Rudraksha Jabala Upanishad is one among the 108
Upanishads. It is a minor Upanishad belonging to Sama Veda.
Rudraksha Upanishad is a dialogue between Lord Kalagnirudra (Lord Shiva) and Yogi Bhusunda. Bhusunda wants to know about the benefits and the origin of Rudraksha beads. Lord Shiva says that Rudrakshas originally fell from his eyes and are very sacred. The mere utterance of its name can wash away sins.
