A practice from the Hindu Kundalini Yoga tradition which is mentioned by Samael Aun Weor but not taught or practiced. It is described by Swami Sivananda in his book Kundalini Yoga: "Khechari Mudra: ‘Kha’ means Akasa and ‘Chari’ means to move. The Yogi moves in the Akasa. The tongue and the mind remain in the Akasa. Hence this is known as Khechari Mudra. This Mudra can be performed by a man, only if he has undergone the preliminary exercise under the direct guidance of a Guru, who is practising Khechari Mudra." This mudra requires the cutting of the tendon of the tongue. About it, Samael Aun Weor stated: "A Yogi/Yogini can live with their physical body throughout the millions of years and move about within the pure Akasha without the necessity of cutting the inferior tendon of his tongue, as the Kechari-Mudra unfortunately teaches. What is important is to attain the Elixir of Long Life and to become strong with the practice of internal meditation." (Kundalini Yoga)
