Khecari Mudra is a hatha yoga mudra practice carried out by curling the tip of the tongue back into the mouth until it reaches above the soft palate and into the nasal cavity. In the full practice, the tongue is made long enough to do this with many months of daily tongue stretching and by gradually severing the lingual frenulum with a sharp implement over a period of months. Variant spellings include Khechari Mudra, Kecharimudra,and Kechari Mudra. Mudra when used in yoga, is a position that is designed to awaken spiritual energies in the body. According to Swami Kriyananda, "The assumption of this mudra helps to hasten the advent of deep spiritual states of consciousness." Swami Sivananda described Khecari Mudra as "the best of all Mudras."
A hathayoga text, the Khecarividya, states that khechari mudra enables one to raise Kundalini and access various stores of amrita in the head, which subsequently flood the body. Bhattacharyya defines Khecarī Mudra as the "Yogic posture which bestows spiritual attainment and enables one to overcome disease and death." He explains that "Kha denotes brahman, and that power which moves (cara) as the kinetic energy of brahman is known (as) Khecari."
Singh defines Khecarī Mudra as "the bliss of the vast expanse of spiritual consciousness, also known as divya mudra or Shivavastha (the state of Shiva)." He further identifies it in a higher sense with the end state of consciousness, and not just the physical posture used to achieve that end: "So Khecari Mudra in Shaiva agama means a state of universal consciousness which is the state of Shiva."
In recent times, khecari mudra was taught by Paramahansa Yogananda as a part of Kriya Yoga practice. Yogananda stated that: "Through the performance of Kechari Mudra, touching the tip of the tongue to the uvula, or "little tongue," (or placing it in the nasal cavity behind the uvula), that divine life-current draws the prana from the senses into the spine and draws it up through the chakras to Vaishvanara (Universal Spirit), uniting the consciousness with spirit.
