It is generally said that in present times, the world has assumed the form of a global village. But this is only half the truth. Modern technology and communications have, of course, greatly reduced distances across the world. But the closeness thus produced is of a purely physical nature. Modern technology may have bridged certain gaps, bringing the external world closer together, but the task of bringing unity into the internal world has yet to be accomplished.

What is spiritual unity? Let us take a very simple example. When you live in a crowded settlement, the walls all around give you a sense of limitation. You experience the friction of living in close contact with others and you suffer from mental tension. Later, when you emerge from that dense human settlement into open, natural surroundings you immediately feel that your tension has evaporated and you have once again become serene. The feeling of separateness is replaced by an all-pervasive feeling of unity. You immediately become part of a world where there are no boundaries. A sense of universality prevails.

We have all had this experience at one time or another. It shows us what spiritual unity is. It is, in fact, the raising of one's existence to a higher plane. The moment you achieve this, you feel you are emerging from a limited world to become a citizen of an unlimited world. Disunity now disappears, giving way to unity all around.

Although, physically, all human beings appear to be different, spiritually they are one. It is as if spiritual unity between human beings already exists, it does not have to be externally imposed. We have only to make people aware of its existence. Once the outer, artificial veils are removed, what remains will be pure spirituality.

In reality, the various sets of circumstances that confront man in this world lead to drawing of different veils over man's natural propensities. For instance, the veil of material greed produces self-centredness; the veil of jealousy causes him to see himself as being separate from others; the veil of prejudice causes him to discriminate between human beings, and so on.

These veils, in fact, tend to block man's natural urge towards spiritual unity. What is required is to remove these artificial veils in order that the true, inner reality be brought into focus.

The aim of all religions, basically, is to encourage this spiritual unity within man himself and among men. No religion is at variance with another so far as this goal is concerned. The language in which this is set forth may vary from one religion to another, but, without doubt, the main concern of all religions is to produce spiritual unity within and between all human beings. Without spiritual unity, there is little hope of creating peace and harmony throughout the world. And where there is no peace and harmony, the dream of human progress will forever remain elusive.

Now, what is Islam's contribution to spiritual unity? The subject is too vast for more than just a few basic points to be briefly touched on.
