In short, all sections and parties have their aspirations realized in the teachings of Bahá'u'lláh. As these teachings are declared in churches, in mosques and in other places of worship, whether those of the followers of Buddha or of Confucius, in political circles or amongst materialists, all shall bear witness that these teachings bestow a fresh life upon mankind and constitute the immediate remedy for all the ills of social life. None can find fault with any of these teachings, nay rather, once declared they will all be acclaimed, and all will confess their vital necessity, exclaiming, 'Verily this is the truth and naught is there beside the truth but manifest error.' In conclusion, these few words are written, and unto everyone they will be a clear and conclusive evidence of the truth. Ponder them in thine heart. The will of every sovereign prevaileth during his reign, the will of every philosopher findeth expression in a handful of disciples during his lifetime, but the Power of the Holy Spirit shineth radiantly in the realities of the Messengers of God, and strengtheneth Their will in such wise as to influence a great nation for thousands of years and to regenerate the human soul and revive mankind. Consider how great is this power! It is an extraordinary Power, an all-sufficient proof of the truth of the mission of the Prophets of God, and a conclusive evidence of the power of Divine Inspiration. The Glory of Glories rest upon thee. Haifa, 21 September 1921. FOOTNOTES 1 Original Persian text first published Cairo 1922. This translation taken from The Bahá'í World, Vol. XV, pp. 37-43. 2 'Abdu'l-Bahá is obviously referring to the letter from Forel translated above and dated 28 December 1920. 3 'Abdu'l-Bahá refers to His talk at Stanford University, Palo Alto, California, in 1912, which was published in the local newspaper and is also included in the collection of His talks in America, entitled The Promulgation of Universal Peace. 4 There 'Abdu'l-Bahá distinguishes the materialistic and empirical philosophy of the modern West from the standard rationalistic philosophy of the Greeks and Persians, and highlights the difference between theories of the essence of nature and of the origin of man.
