Hesychia (ἡσυχία, which means "quietude," "stillness," or "rest") is mysticism, yes; it is also the historic Christian faith. It is _the_ genuine expression of the Christian faith lived out in continual prayer (1 Thess 5:16-18), exemplified by the righteous who are deeply in communion with God. You just don't see, understand, or appreciate that because you have inherited all the baggage of the West, influenced as it is by rationalist Scholasticism and naturalism, then Renaissance humanism (fueled by a resurgence of Plato and Neo-Platonic thought, Kabbalah, hermeticism, and neo-gnosticism), then the "Enlightenment," then postmodernism, and on and on. Over the centuries, these have served only to push the West farther and farther away from its ancient Christian heritage which once was almost identical to the East (including Christian mysticism, especially as practiced by the monastics, be they in the Egyptian deserts or Irish bogs). Hesychia (quietude, stillness) is what was practiced by the ascetic prophets of the Old Testament (e.g., Elijah, Elisha, Isaiah, Ezekiel, Daniel, etc.), and also practiced by apostles like Paul and John, who frequently found themselves "in the Spirit" and having mystical experiences themselves (e.g., caught up to the Third Heaven and seeing things too wonderful and impossible to deacribe, or being present in the heavenly throne room of God and Christ, with the twenty-four elders, the living creatures, and innumerable angels surrounding the throne). Hesychia is Christian mysticism, but it is not to be conflated or confused with far eastern (e.g., Hindu, Buddhist) mystical practices like Zen, etc. The holy fathers have long taught that those practices were, in fact, copied from the early Christians by the pagans and distorted and corrupted. If you would like to learn more, I would highly recommend you get a copy of "The Triads" by St. Gregory Palamas. A recent translation of the whole work was made by Fr. Peter Chamberas. I also recommend getting and reading "The Way of a Pilgrim," translated by Olga Savin with foreword by Fr. Thomas Hopko (this edition is published, unfortunately, by Shambhala Classics, which also publishes books within the aforementioned pagan mystical traditions).

The Holy Name of Our Lord Jesus Christ, True God & True Man; The Alpha and The Omega; By Which Name Alone IS man saved; devils Exorcised; Miracles of Healing granted; The Holy Eucharist Confected upon our Altars; Sins Forgiven; Salvation wrought; and Every good work performed.., God Is Mystery, being Caught up In The Holy Spirit, Who Proceeds From The Father and The Son..Is The Mystical Life...that has progressed from the head to the heart.

"The Prayer IS Love"

@@gailkoelmeyer7650 "Who Proceeds From The Father and -The Son- " The _filioque_ was not originally in the Nicene-Constantinopolitan Creed, as the creed deals specifically with the ontological natures of the Trinity. Unbegotten Father, Begotten Son, Spirit proceeding from the Father. The only sense in which the Spirit can be said to proceed from the Father _and_ the Son is economically, in time and space, after Jesus ascends back to the Father, requests of the Father, and sends the Spirit on Pentecost. It's in the economy of salvation only, but the insertion of the _filioque_ into the Creed was a western innovation (condemned as a heresy, in fact) and distorts the Trinity.

​@HickoryDickory86 in what way distorts it?
