The Amritabindu Upanishad is one of the minor Upanishads.
It is one of the five Bindu Upanishads, attached to the Atharvaveda, and one of twenty Yoga Upanishads in the four Vedas.
It is notable for presenting a six limbed Yoga system which matches five stages of the eight stage Patanjali’s Yogasutras and offering a unique, different sixth stage.
It is listed at number 20 in the serial order of the Muktika enumerated by Rama to Hanuman in the modern era anthology of 108 Upanishads.
