Problem: 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.

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".

Problem: Stanley Kirk Burrell (born March 30, 1962), better known by his stage name MC Hammer (or simply Hammer), is an American hip hop recording artist, dancer, record producer and entrepreneur. He had his greatest commercial success and popularity from the late 1980s, until the early 1990s. Remembered for his rapid rise to fame, Hammer is known for hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album.

Before Hammer's successful music career (with his mainstream popularity lasting approximately between 1988 and 1998) and his "rags-to-riches-to-rags-and-back saga", Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as K.B. and then eventually M.C. Hammer once it was produced), was later released on Gibson's album Change of Heart (1988). This was Contemporary Christian music's first rap hit ever. Burrell also produced "Son of the King" at that time, releasing it on his debut album. "Son of the King" showed up on Hammer's debut album Feel My Power (1987), as well as the re-released version Let's Get It Started (1988). With exception to later remixes of early releases, Hammer produced and recorded many rap songs that were never made public, yet are now available on the Internet. Via his record labels such as Bust It Records, Oaktown Records and FullBlast, Hammer has introduced, signed and produced new talent including Oaktown's 3.5.7, Ho Frat Hoo!, the vocal quintet Special Generation, Analise, James Greer, One Cause One Effect, B Angie B, The Stooge Playaz, DASIT (as seen on ego trip's The (White) Rapper Show), Teabag, Common Unity, Geeman and Pleasure Ellis; both collaborating with him and producing music of their own during his career. At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.
