Islam is the only religion widely spread in the whole world yet I am not hearing of any saints and sufis that were famous during mughal rule and before that... If anyone want to do meditation and take the guidance it is difficult to find any teachers or saints from whom to take teachings... I would like to know how a muslim can survive in this era

If a Muslim follows the Qur'an... they will succeed. "Would you follow any word other than this Qur'an?"
