It is dedicated to the rudraksha, a seed used as prayer beads, regarded sacred to the god Shiva.
The Rudraksha Jabala Upanishad begins with an invocation to Brahman, the Supreme Reality for the well-being of all parts of the body, the prana (spirit), and speech.
[3][4] Sage Bhusunda, also known as Sanatkumara, asks Kalagni Rudra, a destructive form of Shiva who is identified with Bhairava, about the origins of the Rudraksha and the benefits of wearing it.
Four types of rudraksha – white, red, yellowish, and black – are declared fit for four Varnas or castes – Brahmin, Kshatriya, Vaishya, and Shudra, respectively.
A rudraksha can be worn on the hair tuft, 30 around the head, 36 in a necklace, 16 on each arm, 12 on each wrist, 15 around the shoulders, and 108 in the yajnopavita (sacred thread).
One should also wear them around the waist, as earrings, and as a rosary.These beads are believed to possess powerful metaphysical qualities that can positively influence the wearer's physical, mental, and spiritual well-being.
The sages include Nidagha, Jadabharata, Dattatreya, Katyayana, Bharadvaja, Kapila, Vasishtha, and Pippalada.
One attains greatness and becomes a guru (teacher) and an expert in mantras by studying the scripture daily.
The Brahmin who chants this Upanishad in the evening is absolved of sins he committed during the day.
One is freed of the sins of killing a Brahmin, stealing gold, drinking alcohol, and having coitus with the wife of his guru.
