During the many centuries that have passed, humankind has moved through winding, misleading, hard, difficult paths and has encountered various obstacles with a pained body and injured feet in order to reach the main road. This main road is the road that we will see at the time of the Reappearance [of Imam Mahdi]. It is the world that we will see at the time of the Reappearance. In a sense, humankind’s movement will start from that point.
