Śrī Vidyā (also spelled "Shri" or "Shree" Vidya. विद्या (IAST: vidyā) is "knowledge, learning, lore, science".) is a Hindu Tantric religious system devoted to the Goddess as Lalitā Tripurasundarī ("Beautiful Goddess of the Three Cities"), Bhuvaneshvari etc. A thousand names for this form of Devī are recited in the Lalitā Sahasranāma, which includes Śrī Vidyā concepts. The sect accepts and aims to provide both material prosperity and self-realisation. It has an extensive literature. Details of belief vary in different texts but the general principles are similar to those found in Kashmir Shaivism. There are various schools, including the so-called left-handed and right-handed practice. Initiation must be from a guru. Many Sri Vidya mantras are available in print but they are often considered more potent in the context of the guru's initiation.
In the principally Shakta theology of Śrī Vidyā the goddess is supreme, transcending the cosmos that is her manifestation. She is worshiped in the form of a mystical diagram (Sanskrit: yantra), a central focus and ritual object composed of nine intersecting triangles, called the Sri Yantra or śrīcakra The Meru Chakra is a three-dimensional form of this, made of rock crystal or metal, often a traditional alloy of silver, antimony, copper, zinc and pewter that is held to enhance the flow and generation of its beneficial energies, covered in gold. Subhash Kak argues that this is the yantra described in the Śvetāśvatara Upanisad.
Mantras are believed to reveal the unity of the deity, the guru and initiate and the mantra or sound syllable Itself. The first mantra given to initiates is the Bala Tripurasundari Mantra. Here the Goddess is visualized as a small child. The next level mantra is the fifteen-lettered Panchadasi or Panchadasakshari Mantra. A higher mantra is the sixteen-lettered Shodasi or Shodashakshari Mantra.
