The Sufis were practitioners of the esoteric mystic traditions within an Islam at a certain point. Sufism is defined by the Sufi master or Pir (Sufism) or fakeer or Wali in the language of the people by dancing and singing and incorporating various philosophies, theologies, ideologies and religions together (e.g., Christianity, Judaism, Paganism, Platonism, Zoroastrianism, Buddhism, Hinduism, Sikhism and so forth with time). Famous Sufi masters are Rumi, Shadhili, Sheikh Farid, Bulleh Shah, Shah Hussain, Shams Tabrizi, Waris Shah, al-Ghazali, Mian Mir, Attar of Nishapur, Amir Khusrow, Salim Chishti. See many more famous Sufis at the List of Sufis. The Sufis were considered by many to have divine revelations with messages of peace, tolerance, equality, pluralism, love for all and hate for no one, humanitarians, philosophers, psychologists and much more. Many had the teaching if you want to change the world, change yourself and you will change the whole world. The views of the Sufi poets, philosophers and theologians have inspired multiple forms of modern-day academia as well as philosophers of other religions. See also Blind men and an elephant. But undoubtedly, the most influential Sufi scholar to have embraced the world is Jalaluddin Muhammad Rumi. He was born in 1207 AD in a northern province of Afghanistan, however, he later had to seek refuge in Turkey following the invasion of Afghanistan by Mongols. Rumi, through his poetry and teachings, propagated inter-faith harmony like none other. He served as a uniting figure for people of different faiths and his followers included Muslims, Christians and Jews. Even today, Rumi's popularity does not cease to exist within the Sufi Muslim community and his message of peace and harmony transcends religious and geographical boundaries.
