Although the concept of the Mahdi is more wide spread than the Muslim community, yet its detailed features, as determined by Islam, meet more fully all the aspirations attached to it since the dawn of history. They are in greater conformity with the feelings and sentiments of the oppressed and the persecuted of all times. It is Islam which has given a concrete shape to an abstract idea.
It is no longer necessary to look forward to an unknown saviour who may come into the world at a distant future. The saviour is already here and we simply have to look for the day when the circumstances are ripe for him to appear and begin his great mission. The Mahdi is no longer an idea. He is no longer a prophecy. We need not wait for his birth. He already exists actually and we only wait for the inauguration of his role.
He is a specific entity living among us in his real human form and shares our hopes and disappointments and our joys and griefs. He witnesses all the acts of oppression and persecution which are perpetrated on the face of the earth and, somehow or another, he himself is affected by them. He is anxiously awaiting the moment when he will be able to extend his helping hand to everyone whom any wrong has been done and be able to eradicate injustice and oppression completely.
Although this Awaited Saviour is living among us, waiting for the appointed moment for his advent, yet he is ordained not to proclaim himself nor to disclose his identity. It is evident that the concept of the Mahdi, with its Islamic features, shortens the gap between the oppressed and the expected saviour. It spans the bridge between them, howsoever long the period of waiting may be.
When we are asked to believe that the Mahdi is a particular person already living a normal life, we are also expected to believe that the idea of absolute eradication of every kind of injustice and oppression by the Mahdi has already been embodied in the person of the Awaited Saviour who will reappear while he will be, as the tradition says, 'owing no allegiance to any tyrant'. The belief in him means the belief in eradication of all evils in a concrete form.
The tradition urges the believers in the Mahdi to keep on waiting for him and to continue looking forward for solace. The idea is to establish a close spiritual and intuitive link between the believers, on the one hand, and the Mahdi and all that he stands for, on the other.
