In Hinduism, Kundalini (Sanskrit: कुण्डलिनी, romanized: kuṇḍalinī, lit. 'coiled snake', pronunciation ) is a form of divine feminine energy (or Shakti) 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 or the formless aspect of the Goddess. This energy in the body, when cultivated and awakened through tantric practice, is believed to lead to spiritual liberation. Kuṇḍalinī is associated with Parvati 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.

Kuṇḍalinī awakenings are said to occur by a variety of methods. Many systems of yoga focus on awakening Kuṇḍalinī through: meditation; pranayama breathing; the practice of asana and chanting of mantras. Kundalini Yoga is influenced by Shaktism and Tantra schools of Hinduism. It derives its name from its focus upon the awakening of kundalini energy through regular practice of Mantra, Tantra, Yantra, Asanas or Meditation.
