The Rudrayamala (Sanskrit: रुद्रयामल; IAST:Rudrayāmala) also known as Rudra Yamala, Rudrayāmala Tantra, Rudra-Yamala, or Parātriṁśaka, is considered one of the most important Sanskrit Tantric texts.[1] It is divided into 64 chapters.[1] Though its exact date of composition is unknown.[2]
Initiation and rituals
A section of the text known as the Rudrayāmala-Uttaratantra outlines specific prohibitions regarding who can initiate whom into spiritual mantras. It states that a husband should not initiate his wife, a father should not initiate his children, and a man should not initiate his brother. These strict rules reflect an older tradition of Tantrism that was later relaxed or abolished by newer texts such as the Mahānirvāṇatantra.[2]
Goddess Tara
It records that the Vāmācāra (left-hand path) practices associated with Devi Tara's worship were introduced by the sage Vashistha, who reportedly received his instructions directly from the Buddha.[3] Additionally, the text details the iconography of the goddess Ugra-Tara, highlighting similarities between Tara and the goddess Kali; it notes that both deities are depicted standing upon a supine, corpse-like Shiva.[3]
Alchemy and science
Beyond theology and rituals, the Rudrayāmala Tantra contains a section dedicated to mercury and early alchemy known as the Rasārṇava-kalpa. Recognizing its historical value to Indian science, the National Commission for History of Science published an English translation of this specific section.[4]
