Background: Swami Vivekananda (Bengali: [Sami bibekanondo] ( listen); 12 January 1863 - 4 July 1902), born Narendranath Datta (Bengali: [norendronath doto]), was an Indian Hindu monk, a chief disciple of the 19th-century Indian mystic Ramakrishna.  He was a key figure in the introduction of the Indian philosophies of Vedanta and Yoga to the Western world and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century. He was a major force in the revival of Hinduism in India, and contributed to the concept of nationalism in colonial India. Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission.
Context: Vivekananda propagated that the essence of Hinduism was best expressed in Adi Shankara's Advaita Vedanta philosophy. Nevertheless, following Ramakrishna, and in contrast to Advaita Vedanta, Vivekananda believed that the Absolute is both immanent and transcendent. According to Anil Sooklal, Vivekananda's neo-Advaita "reconciles Dvaita or dualism and Advaita or non-dualism". Vivekananda summarised the Vedanta as follows, giving it a modern and Universalistic interpretation:  Each soul is potentially divine. The goal is to manifest this Divinity within by controlling nature, external and internal. Do this either by work, or worship, or mental discipline, or philosophy--by one, or more, or all of these--and be free. This is the whole of religion. Doctrines, or dogmas, or rituals, or books, or temples, or forms, are but secondary details.  Nationalism was a prominent theme in Vivekananda's thought. He believed that a country's future depends on its people, and his teachings focused on human development. He wanted "to set in motion a machinery which will bring noblest ideas to the doorstep of even the poorest and the meanest".  Vivekananda linked morality with control of the mind, seeing truth, purity and unselfishness as traits which strengthened it. He advised his followers to be holy, unselfish and to have shraddha (faith). Vivekananda supported brahmacharya (celibacy), believing it the source of his physical and mental stamina and eloquence. He emphasised that success was an outcome of focused thought and action; in his lectures on Raja Yoga he said, "Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, that is the way great spiritual giants are produced".
Question: Did he have any other philosophies
Answer: Do this either by work, or worship, or mental discipline, or philosophy--by one, or more, or all of these--and be free.

Background: Chayefsky was born in The Bronx, New York City to Russian Jewish immigrants Harry and Gussie Stuchevsky Chayefsky who came from Moscow to New York in 1907. He had two older brothers, William and Isidor. He spent part of his youth in Mount Vernon, New York.
Context: Returning to the United States, Chayefsky worked in his uncle's print shop, Regal Press, an experience which provided a background for his later teleplay, Printer's Measure (1953), as well as his story for the movie As Young as You Feel (1951). Kanin enabled Chayefsky to spend time working on his second play, Put Them All Together (later known as M is for Mother), but it was never produced. Producers Mike Gordon and Jerry Bressler gave him a junior writer's contract. He wrote a story, The Great American Hoax, which sold to Good Housekeeping but was never published.  He relocated to Hollywood, where he met his future wife Susan Sackler, and the couple married in February 1949. Failing to find work on the West Coast, Chayefsky returned to New York.  During the late 1940s, he began working full-time on short stories and radio scripts, and during that period, he was a gagwriter for radio host Robert Q. Lewis. Chayefsky later recalled, "I sold some plays to men who had an uncanny ability not to raise money." During 1951-52, Chayefsky wrote adaptations for radio's Theater Guild on the Air: The Meanest Man in the World (with James Stewart), Cavalcade of America, Tommy (with Van Heflin and Ruth Gordon) and Over 21 (with Wally Cox).  His play The Man Who Made the Mountain Shake was noticed by Elia Kazan, and his wife, Molly Kazan, helped Chayefsky with revisions. It was retitled Fifth From Garibaldi but was never produced. In 1951, the movie As Young as You Feel was adapted from a Chayefsky story.
Question: what did he do after the war?
Answer: Returning to the United States, Chayefsky worked in his uncle's print shop,

Background: Allen was born Allan Stewart Konigsberg in the Brooklyn borough of New York City, New York. He and his sister, Letty (b. 1943), were raised in Midwood, Brooklyn. He is the son of Nettie (nee Cherry; November 8, 1906 - January 27, 2002), a bookkeeper at her family's delicatessen, and Martin Konigsberg (December 25, 1900 - January 8, 2001), a jewelry engraver and waiter. His family was Jewish, and his grandparents immigrated to the US from Russia and Austria and spoke Yiddish, Hebrew, and German.
Context: Allen is a passionate fan of jazz, featured prominently in the soundtracks to his films. He began playing the clarinet as a child and took his stage name from clarinetist Woody Herman. He has performed publicly at least since the late 1960s, notably with the Preservation Hall Jazz Band on the soundtrack of Sleeper. One of his earliest televised performances was on The Dick Cavett Show on October 20, 1971.  Woody Allen and his New Orleans Jazz Band have been playing each Monday evening at Manhattan's Carlyle Hotel for many years (as of 2011, specializing in classic New Orleans jazz from the early twentieth century). He plays songs by Sidney Bechet, George Lewis, Johnny Dodds, Jimmie Noone and Louis Armstrong. The documentary film Wild Man Blues (directed by Barbara Kopple) documents a 1996 European tour by Allen and his band, as well as his relationship with Previn. The band has released two CDs: The Bunk Project (1993) and the soundtrack of Wild Man Blues (1997). In a 2011 review of a concert by Allen's jazz band, critic Kirk Silsbee of the L.A. Times suggested that Allen should be regarded as a competent musical hobbyist with a sincere appreciation for early jazz: "Allen's clarinet won't make anyone forget Sidney Bechet, Barney Bigard or Evan Christopher. His piping tone and strings of staccato notes can't approximate melodic or lyrical phrasing. Still his earnestness and the obvious regard he has for traditional jazz counts for something."  Allen and his band played the Montreal International Jazz Festival on two consecutive nights in June 2008. For many years, Allen wanted to make a film about the origins of jazz in New Orleans. The film, tentatively titled American Blues, would follow the vastly different careers of Louis Armstrong and Sidney Bechet. Allen stated that the film would cost between $80 and $100 million and is therefore unlikely to be made.
Question: When did Allen start playing music?
Answer:
He has performed publicly at least since the late 1960s,
