Yogini in the context of "Greater Tibet"

Chamunda (Sanskrit: चामुण्डा, IAST: Cāmuṇḍā), also known as Chamundeshwari, Chamundi or Charchika, is a fearsome form of Chandi, the Hindu mother goddess, Mahadevi and is one of the seven Matrikas.

She is also one of the chief Yoginis, a group of sixty-four or eighty-one Tantric goddesses, who are attendants of the warrior goddess Parvati. The name is a combination of Chanda and Munda, two demons whom Chamunda killed. She is closely associated with Mahakali or Durga.

A yogi is a practitioner of Yoga, including a sannyasin or practitioner of meditation in Indian religions. The feminine form, sometimes used in English, is yogini.

Yogi has since the 12th century CE also denoted members of the Nath siddha tradition of Hinduism, and in Hinduism, Buddhism and Jainism, a practitioner of tantra. In Hindu mythology, the god Shiva and the goddess Parvati are depicted as an emblematic yogi–yogini pair.

The Mahavidya (Sanskrit: महाविद्या, IAST: Mahāvidyā, lit. Great Wisdoms) are a group of ten Hindu Tantric goddesses. The ten Mahavidyas are usually named in the following sequence: Kali, Tara, Tripura Sundari, Bhuvaneshvari, Bhairavi, Chhinnamasta, Dhumavati, Bagalamukhi, Matangi and Kamalatmika. Nevertheless, the formation of this group encompasses divergent and varied religious traditions that include yogini worship, Shaivism, Vaishnavism, and Vajrayana Buddhism.

The development of the Mahavidyas represents an important turning point in the history of Shaktism as it marks the rise of the Bhakti aspect in Shaktism, which reached its zenith in 1700 CE. First sprung forth in the post-Puranic age, around 6th century CE, it was a new theistic movement in which the supreme being was envisioned as female. A fact epitomized by texts like Devi-Bhagavata Purana, especially its last nine chapters (31–40) of the seventh skandha, which are known as the Devi Gita, and soon became central texts of Shaktism.

The Kagyu school, also transliterated as Kagyü, or Kagyud (Tibetan: བཀའ་བརྒྱུད།, Wylie: bka' brgyud), which translates to "Oral Lineage" or "Whispered Transmission" school, is one of the main schools (chos lugs) of Tibetan Buddhism. The Kagyu lineages trace themselves back to the 11th century Indian Mahasiddhas Naropa, Maitripa and the yogini Niguma, via their student Marpa Lotsawa (1012–1097), who brought their teachings to Tibet. Marpa's student Milarepa was also an influential poet and teacher.

The Tibetan Kagyu tradition gave rise to a large number of independent sub-schools and lineages. The principal Kagyu lineages existing today as independent schools are those which stem from Milarepa's disciple, Gampopa (1079–1153), a monk who merged the Kagyu lineage with the Kadam tradition. The Kagyu schools which survive as independent institutions are mainly the Karma Kagyu, Drikung Kagyu, Drukpa Lineage and the Taklung Kagyu. The Karma Kagyu school is the largest of the sub-schools, and is headed by the Karmapa. Other lineages of Kagyu teachings, such as the Shangpa Kagyu, are preserved in other schools.

There is no formal canonization process in Hinduism, but over time many men and women have reached the status of saints among their followers and among Hindus in general. Hindu saints have often renounced the world, and are variously called gurus, sadhus, rishis, swamis, muni, yogis, yoginis and other names.

Many people conflate the terms "saint" and "sant", because of their similar meanings. The term sant is a Sanskrit word "which differs significantly from the false cognate, 'saint'..." Traditionally, "sant" referred to devotional Bhakti poet-saints of two groups: Vaishnava and a group that is referred to as "Saguna Bhakti".

The Yogini temples of India are 9th- to 12th-century roofless hypaethral shrines to the yoginis, female masters of yoga in Hindu tantra, broadly equated with goddesses especially Parvati, incarnating the sacred feminine force. They remained largely unknown and unstudied by scholars until late in the 20th century. Several of the shrines have niches for 64 yoginis, so are called Chausath Yogini Temples (Chausath Yogini Mandir, from चौसठ, Hindi for 64, also written Chaunsath or Chausathi); others have 42 or 81 niches, implying different sets of goddesses, though they too are often called Chausath yogini temples. Even when there are 64 yoginis, these are not always the same.

The extant temples are either circular or rectangular in plan; they are scattered over central and northern India in the states of Uttar Pradesh, Madhya Pradesh, and Odisha. Lost temples, their locations identified from surviving yogini images, are still more widely distributed across the subcontinent, from Delhi in the north and the border of Rajasthan in the west to Greater Bengal in the east and Tamil Nadu in the south.

Niguma is considered one of the most important and influential yoginis and Vajrayana teachers of the 10th or 11th century in India. She was a dakini, and one of the two female founders of the Shangpa Kagyu school of Vajrayana Buddhism, along with dakini Sukhasiddhi. Her birth name was Shrijnana (or Palgyi Yéshé in Tibetan). Like many of the mahasiddhas and Tantric practitioners of the time, Niguma was known by several names both during her lifetime and afterwards. She was called Yogini Vimalashri, or Vajradhara Niguma, or Jñana (wisdom) Dakini Adorned with Bone (ornaments), or The Sister referring to her purported relationship to the great Buddhist teacher and adept Naropa. She was also sometimes called Nigupta, which is explained by the historical Buddhist scholar Taranatha as follows: "The name Nigu accords with the Indian language, which is Nigupta, and is said to mean 'truly secret' or 'truly hidden.' In fact, it is the code-language of the dakinis of timeless awareness."

There is often confusion between the biographical details of Niguma's life and spiritual accomplishments and that of the renowned Vajrayana teacher and mahasiddha Naropa. While the biographical information for Niguma is scarce, what is available often offers details that are identical with the biography of Naropa. While not much can be confirmed about the historical details of Niguma's life, what does remain is the corpus of her teachings and her impact on the founding of the Shangpa Kagyu Buddhist spiritual lineage, known as one of the "“Eight Great Chariots of the Practice Lineages” (Wylie, sgrub brgyud shing rta chen po brgyad), meaning one of the eight great Buddhist spiritual traditions that eventually were transmitted from India to Tibet. The importance of the dakini Niguma as a spiritual practitioner, teacher, and lineage founder continues to the present day.
