Kundalini, in Hinduism is a form of divine feminine energy believed to be located at the base of the spine, in the muladhara. It is an important concept in Śhaiva Tantra, where it is believed to be a force or power associated with the divine feminine. This energy, when cultivated and awakened through tantric practice, is believed to lead to spiritual liberation. Kuṇḍalinī is associated with Paradevi or Adi Parashakti, the supreme being in Shaktism; and with the goddesses Bhairavi and Kubjika. The term, along with practices associated with it, was adopted into Hatha yoga in the 9th century. It has since then been adopted into other forms of Hinduism as well as modern spirituality and New age thought.
