Answer by taking a quote from the following article:

Alejandro Jodorowsky Prullansky (Spanish: [ale'xandro xodo'rofski]; born 17 February 1929) is a Chilean-French filmmaker. Active since 1948, in seventy years of his artistic career Jodorowsky has experienced it in almost all creative forms: writer (in his five facets: novelist, storyteller, poet, playwright and essayist), film director and producer, actor of cinema and theatre, playwright, theatre director, screenwriter, film editor, comics writer, musician, soundtrack composer, philosopher, puppeteer, mime, psychologist and psychoanalyst, draughtsman, painter, eventually sculptor and spiritual guru. Best known for his avant-garde films, he has been "venerated by cult cinema enthusiasts" for his work which "is filled with violently surreal images and a hybrid blend of mysticism and religious provocation". Born to Jewish-Ukrainian parents in Chile, Jodorowsky experienced an unhappy and alienated childhood, and so immersed himself in reading and writing poetry.

Jodorowsky spent almost a decade reconstructing the original form of the Tarot de Marseille. From this work he moved into more therapeutic work in three areas: psychomagic, psychogenealogy and initiatic massage. Psychomagic aims to heal psychological wounds suffered in life. This therapy is based on the belief that the performance of certain acts can directly act upon the unconscious mind, releasing it from a series of traumas, some of which practitioners of the therapy believe are passed down from generation to generation. Psychogenealogy includes the studying of the patient's personality and family tree in order to best address their specific sources. It is similar, in its phenomenological approach to genealogy, to the Constellations pioneered by Bert Hellinger.  Jodorowsky has several books on his therapeutic methods, including Psicomagia: La trampa sagrada (Psychomagic: The Sacred Trap) and his autobiography, La danza de la realidad (The Dance of Reality), which he was filming as a feature-length film in March 2012. To date he has published more than 23 novels and philosophical treatises, along with dozens of articles and interviews. His books are widely read in Spanish and French, but are for the most part unknown to English-speaking audiences.  Throughout his career, Jodorowsky has gained a reputation as a philosopher and scholar who presents the teachings of religion, psychology, and spiritual masters, by molding them into imaginative endeavors. All of his enterprises integrate an artistic approach. Currently, Jodorowsky dedicates much of his time to lecturing about his work.  For a quarter of a century, Jodorowsky held classes and lectures for free, in cafes and universities all over the city of Paris. Typically, such courses or talks would begin on Wednesday evenings as tarot divination lessons, and would culminate in an hour long conference, also free, where at times hundreds of attendees would be treated to live demonstrations of a psychological "arbre genealogique" ("tree of genealogy") involving volunteers from the audience. In these conferences, Jodorowsky would pave the way to building a strong base of students of his philosophy, which deals with understanding the unconscious as the "over-self", composed of many generations of family relatives, living or deceased, acting on the psyche, well into adult lives, and causing compulsions. Of all his work, Jodorowsky considers these activities to be the most important of his life. Though such activities only take place in the insular world of Parisian cafes, he has devoted thousands of hours of his life to teaching and helping people "become more conscious," as he puts it.  Since 2011 these talks have dwindled to once a month and take place at the "Librairie Les Cent Ciels" in Paris.
