Khecarī mudrā

Khecarī mudrā (Sanskrit, खेचरी मुद्रा)[1][2] is a hatha yoga 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.

[12][13] A hatha yoga text, the Khecarīvidyā, states that khechari mudrā enables one to raise Kundalini and access various stores of amrita in the head, which subsequently flood the body.

[16]A tantric Saiva text, the Mālinīvijayottaratantra, warns: [If] his mouth fills with a slightly salty liquid that smells of iron then he should not drink it but spit it out.

[18] Bhattacharyya defines Khecarī Mudrā as the "Yogic posture which bestows spiritual attainment and enables one to overcome disease and death."

"[b][21] Abhinavagupta, in his Tantraloka, states that all other mudras derive from khecarī mudrā, which he describes as "the stance of moving or flying through the void of the supreme consciousness.

[c][10] He 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 directs it up through the chakras to Vaishvanara (Universal Spirit), uniting the consciousness with spirit.
