It depends..................Mu (Japanese/Korean), and Wu (Chinese traditional: 無, simplified: 无 pinyin: wú Jyutping: mou2), is a word which has been roughly translated as "no", "none", "null", "without", and "no meaning". While used in Japanese and Chinese mainly as a prefix to indicate the absence of something (e.g., 無線/无线 musen or wúxiàn for "wireless"), in English it is better known as a response to certain koans and other questions in Zen Buddhism, intending to indicate that the question itself was meaningless.
The best-known mu koan is as follows: A monk asked Zhaozhou Congshen, a Chinese Zen master (known as Jōshū in Japanese), "Has a dog Buddha-nature or not?" Zhaozhou answered, "Wú" (in Japanese, Mu).[1][page needed] Some earlier Buddhist thinkers maintained that animals did have the Buddha-nature, others believed that they did not.[citation needed] Therefore, to answer "no" is to deny their wisdom, whereas to say "yes" is to blindly follow their teachings. Zhaozhou's answer has been interpreted to mean that such categorical thinking is a delusion, that yes and no are both right and wrong. This koan is traditionally used by Rinzai school to initiate students into Zen study.[citation needed]
OR Mu is the name of a hypothetical continent that allegedly existed in one of Earth's oceans, but disappeared at the dawn of human history.
The concept and the name were proposed by 19th century traveler and writer Augustus Le Plongeon, who claimed that several ancient civilizations, such as those of Egypt and Mesoamerica, were created by refugees from Mu — which he located in the Atlantic Ocean.[1] This concept was popularized and expanded by James Churchward, who asserted that Mu was once located in the Pacific.[2]
The existence of Mu was disputed already in Le Plongeon's time. Today, scientists universally dismiss the concept of Mu (and of other lost continents like Lemuria) as physically impossible, since a continent can neither sink nor be destroyed by any conceivable catastrophe, especially not in the short period of time required by this premise.[3][4] Moreover, the weight of all archaeological, linguistic and genetic evidence is contrary to the claim that the ancient civilizations of the New and Old Worlds stemmed from a common ancestral civilization. Mu is today considered to be a fictional place.[5][6]
