Shaktism, also known as Shakti worship, is a Hindu tradition that focuses on the worship of the Divine Mother, known as Shakti. This tradition is based on the belief that the entire universe is a manifestation of the Divine Mother, and she is the source of all energy and power.

In Shaktism, there is no single holy book or scripture that is considered the ultimate authority. Instead, there are a variety of texts and scriptures that are revered by different sects and communities within the tradition. These texts include the Devi Mahatmya, the Devi Bhagavata Purana, and the Lalita Sahasranama.

The Devi Mahatmya, also known as the Durga Saptashati, is a popular text that is considered to be the most important scripture in Shaktism. It is a part of the Markandeya Purana and consists of 700 verses that describe the glory and power of the Divine Mother. This text is often recited during the Navaratri festival, a major celebration in Shaktism.

The Devi Bhagavata Purana is another important text in Shaktism, which focuses on the stories and exploits of the Divine Mother. It is considered to be a part of the Mahapuranas, the eighteen major Hindu scriptures. This text is often recited during religious ceremonies and rituals in Shakti temples.

The Lalita Sahasranama, also known as the Thousand Names of the Divine Mother, is a hymn that praises the various aspects and forms of the Divine Mother. It is a part of the Brahmanda Purana and is considered to be a very powerful mantra in Shaktism. This hymn is often recited during puja (worship) and is believed to bring blessings and protection from the Divine Mother.

Apart from these texts, there are also other scriptures and texts that are considered sacred in Shaktism, such as the Tantras, the Shakta Upanishads, and the Shakta Agamas. These texts contain teachings and practices related to the worship of the Divine Mother and are considered to be important sources of knowledge and wisdom in Shaktism.

In conclusion, while there is no single holy book or scripture in Shaktism, there are various texts and scriptures that are revered and considered sacred by different sects and communities within the tradition. These texts play an important role in the worship and devotion to the Divine Mother, and are seen as a means to connect with her and receive her blessings.
