Xenoglossis: speaking in tongues unknown to the psychic or medium. According to certain classifications the term should cover writing in tongues and glossolalia should be employed for speaking them. [See Xenoglossis]

Xylomancy: Divination by means of wood, practiced particularly in Slavonia. It is the art of reading omens from the position of small pieces of dry wood found in one's path. No less certain presages of future events may be drawn from the arrangement of logs in the fire place, from the manner in which they burn, etc. It is perhaps the survival of this mode of divination which makes the good people say, when a brand is disturbed, that, "they are going to have a visitor." 

Yarbro, (Chelsea Quinn): Author of over 70 novels and numerous short stories, Yarbro is probably best known for her series of historical horror novels about the vampire Count Saint-Germain.  But students of the Michael teachings know her as the author of Messages From Michael, and three other channeled books in that groundbreaking series. The Michael teachings is a channeled philosophy of the mid-causal plane entity Michael (not the Archangel Michael) that involves the study of soul age and a unique personality system that helps people better understand the lessons of the reincarnational cycle. [See Michael teachings]

Yeats, (William Butler): Irish Author and Mystic. William Butler Yeats was born at Dublin in 1866, his father being John Yeats, a talented portrait-painter whose works include a fine likeness of Synge ; and during his boyhood the future author lived chiefly at his native town, and occasionally with his grandparents in County Sligo. At first he intended to make painting his life's work, and, accordingly he entered the Dublin Art School; but he soon left it, having realized that his true bent was for Literature; and in 1887 he went to London, where he became intimate with Mr. Arthur Symons, and subsequently with Mr. George Moore. Prior to this Mr. Yeats had issued a little play, Mosada ; and now his gifts began to develop apace, the result being sundry volumes of beautiful poetry, notably The Wanderings of Oisin and The Wind among the Reeds. At this time, also, the author began to show himself an eminently thoughtful critic of literature; while in 1870 he published a collection of Irish folk tales, and in the preface thereto he observed in relation to his compatriots that " a true literary consciousness—national to the centre—seems gradually to be forming out of all this disguising and prettyfing this penumbra of half-culture. We are preparing likely enough for a new Irish literary movement. . . . ." Nor was the prophecy unfulfilled, for, during the closing decade of the 19th century, the intellectuals of Ireland began to manifest a tense interest in their country's legendary lore, while simultaneously it transpired that the rising generation of writers in Ireland included many men of fine promise. Most of these last regarded Mr. Yeats as their leader, they rallied round him, he returned from London to Ireland, and anon he achieved the founding of the Irish Literary Theatre in Dublin, its raison d'etre being the staging of plays by the new school of Hibernian authors.

This is not the place to detail the Irish artistic revival of the nineties of last century, and the reader may be referred to the monograph thereon by Mr. H. S. Krans, and more especially to Mr. George Moores' Hail and Farewell. Passing to speak of Mr. Yeats' contributions to the literature of Mysticism, these are mostly contained in a volume of collected essays, Ideas of Good and Evil; and prominent among them are studies of the mystic element in Blake and Shelley, while another notable paper is one concerned with " The Body of the Father Christian Rosencrux." But still more important than these, perhaps, is a long study of " Magic," contained in the same volume, and here the author begins by bravely stating his creed : "I believe in the practice and philosophy of what we have agreed to call magic, and what I must call the evocation of spirits, though I do not know what they are, in the power of creating magical illusions, in the visions of truth in the depths of the mind when the eyes are closed. ....."

After this declaration he tells how once an acquaintance of his, gathering together a small party in a darkened room, held a mace over " a tablet of many colored squares, at the same time repeating " a form of words " ; and straightway Mr. Yeats found that his " imagination began to move of itself, and to bring before me vivid images. . . . ." He goes on to descant on these visions, while in the remainder of his essay he offers some details about superstitions in remote parts of Ireland; and also furnishes sundry examples of thought-transmission and the like, most of them fresh and interesting.

But the author's interest in the supernatural does not transpire only in his prose, and, turning to his poems, one finds them permeated by a curious kind of mysticism which is perhaps essentially Celtic. For Mr. Yeats, it would seem, is only incidentally interested in holding communications with the dead, or with the spirit-world ; yet, like old bards of his native Ireland, he seems to find inanimate nature a living reality, he seems to have a strange intimacy therewith. A dreamer of dreams and a beholder of visions, he frequently crystallizes these in his verse; but the mystic element in his output consists pre-eminently in this, that he appears to hold actual converse with all those things which to ordinary men are no more than lifeless— with flowers and trees, with rivers, lakes and mountains.

Yeti: Also known as the abominable snowman, the Yeti is a supposed large primate-like creature reported to live in the Himalayas. Most mainstream scientists and experts consider current evidence of the yeti's existence to be unpersuasive, and the result of hoaxes, legend, or misidentification of mundane creatures. Still, the yeti remains one of the most famous creatures in cryptozoology.

Yoga: is a form of mysticism that developed on the Indian subcontinent in the Hindu cultural context. Its origin is impossible to trace, because it dates back to before recorded history. The word Yoga originates from the Sanskrit word "Yuj" ("to yoke") and is generally translated as "union" or "integration". According to Yoga experts, the union referred to by the name is that of the individual soul ("atma") with the cosmos, or the Supreme ("Brahma").

Yoga has both a philosophical and a practical dimension. The philosophy of yoga ("union") deals with the nature of the individual soul and the cosmos, and how the two are related. The practice of yoga, on the other hand, can be any activity that leads or brings the practitioner closer to this mystical union - a state called self-realization. Over thousands of years, special practical yoga techniques have been developed by experts in yoga, who are referred to as Yogis (male) and Yoginis (female). These Yoga techniques cover a broad range, encompassing physical, mental, and spiritual activities. Traditionally, they have been classified into four categories or paths: the path of meditation (Raja Yoga), the path of devotion (Bhakti Yoga), the path of selfless service to the Divine (Karma Yoga), and the path of intellectual analysis or the discrimination of truth and reality (Jnana Yoga). The most conspicuous form of yoga in the West, Hatha Yoga - consisting of various physical and breathing exercises and purification techniques - is actually the third and the fourth stages of Ashtanga Yoga of Yoga Sutras by Patanjali.  [See Yoga]

Yoga when used as a form of alternative medicine is a combination of breathing exercises, physical postures, and meditation, practiced for over 5,000 years.
 

Yogi or Yogin: (Sans.) A devotee, one who practices the Yoga system. There are various grades and kinds of Yogis, and the term has now become in India a generic name to designate every kind of ascetic.

Young soul: From the Michael teachings, someone in the third of the five main physical-plane soul ages, which emphasizes lessons about worldly success. Independence and the ability to get what one wants out of life are the driving force of the Young Soul stage.

Today, Yule is a principle religious festival in Wiccan, Asatru, and other Neopagan practices.
