Bhasmajabala Upanishad (भस्मजाबाल उपनिषत्) is one of the minor Shaiva Upanishads of Hinduism written in Sanskrit language. It is associated with the Atharvaveda. The Bhasmajabala Upanishad, in a manner similar to Brihajjabala Upanishad and Akshamalika Upanishad describes Vibhuti (Bhasma) or sacred ash, and Rudraksha beads as symbols and for body art. The text describes how the ash and beads are to be produced, its application on the body. The importance of holy city of Varanasi and its Shiva temple are mentioned in the text. Klaus Klostermaier classifies the text along with the Brihajjabala Upanishad, the Rudrakshajabala Upanishad, the Kalagni Rudra Upanishad and the Akshamalika Upanishad as Shaiva texts that explain symbolism of rites and objects of worship in Shaivism. The date of composition and the author of this text are unknown. Like most sectarian Upanishads, the text is likely a late medieval, post-12th century era Upanishad and it is neither part of the 17th century compilation of 50 important Hindu Upanishads published by Mughal era Dara Shikoh, nor part of the 18th-century anthology of 52 popular Upanishads in North India published by Colebrooke, nor is it found in the Bibliotheca Indica anthology of popular Upanishads in South India by Narayana. In a Telugu language anthology of 108 Upanishads of the Muktika in the modern era, narrated by Rama to Hanuman, it is listed at serial number 87. The manuscripts of this and related Saiva Upanishads, states Friedrich Otto Schrader, exist in different versions in North India and South India, with differences in content, how the sections are arranged and length, in the Grantha and Devanagari palm leaf manuscript compilations. The Bhasmajabala Upanishad is presented in two parts. The first part, with 17 verses, explained by Bhusunda Jabala, prescribes the procedure for making the Bhashma and its smearing; the second part, with 52 verses, narrates the conversation between Bhusunda Jabala and Shiva giving details about the Gods to be worshipped, and procedures for worship.
