A conquest can be a praiseworthy thing, and there are times when war becomes the powerful basis of peace, and ruin the very means of reconstruction. If, for example, a high-minded sovereign marshals his troops to block the onset of the insurgent and the aggressor, or again, if he takes the field and distinguishes himself in a struggle to unify a divided state and people, if, in brief, he is waging war for a righteous purpose, then this seeming wrath is mercy itself, and this apparent tyranny the very substance of justice and this warfare the cornerstone of peace. Today, the task befitting great rulers is to establish universal peace, for in this lies the freedom of all peoples.—The Secret of Divine Civilization, pp. 70–71. Unity of East and West Another factor which will help in bringing about universal peace is the linking together of the East and the West. The Most Great Peace is no mere cessation of hostilities, but a fertilizing union and cordial cooperation of the hitherto sundered peoples of the earth which will bear much precious fruit. In one of His talks in Paris, ‘Abdu’l-Bahá said:— In the past, as in the present, the Spiritual Sun of Truth has always shone from the horizon of the East. In the East Moses arose to lead and teach the people. On the Eastern horizon rose the Lord Christ. Muḥammad was sent to an Eastern nation. The Báb arose in the Eastern land of Persia. Bahá’u’lláh lived and taught in the East. All the great spiritual teachers arose in the Eastern world. But although the Sun of Christ dawned in the East, the radiance thereof was apparent in the West, where the effulgence of its glory was more clearly seen. The divine light of His teaching shone with a greater force in the Western world, where it has made more rapid headway than in the land of its birth. In these days the East is in need of material progress and the West is in need of a spiritual ideal. It would be well for the West to turn to the East for illumination, and to give in exchange its scientific knowledge. There must be this interchange of gifts. The East and the West must unite to give to each other what is lacking. This union will bring about true civilization where the spiritual is expressed and carried out in the material. Receiving thus, the one from the other, the greatest harmony will prevail, all people will be united, a state of great perfection will be attained, there will be a firm cementing, and this world will become a shining mirror for the reflection of the attributes of God.
