His teachings are thus very completely preserved, and they cover a very wide range of subjects. With many of the problems of both East and West He dealt more fully than His Father had done, giving more detailed applications of the general principles laid down by Bahá’u’lláh. A number of His Writings have not yet been translated into any Western language but enough is already available to give deep and full knowledge of the more important principles of His teaching. He spoke Persian, Arabic and Turkish. In His Western tours His talks and addresses were always interpreted, obviously losing much of their beauty, eloquence and force in the process, yet such was the power of the Spirit which accompanied His words that all who heard Him were impressed. Station of ‘Abdu’l-Bahá The unique station assigned to ‘Abdu’l-Bahá by the Blessed Perfection is indicated in the following passage written by the latter:—“When the ocean of My presence hath ebbed and the Book of My Revelation is ended, turn your faces towards Him Whom God hath purposed, Who hath branched from this Ancient Root.” And again:—“ ... refer ye whatsoever ye understand not in the Book to Him Who hath branched from this mighty Stock.” ‘Abdu’l-Bahá Himself wrote the following:—“In accordance with the explicit text of the Kitáb-i-Aqdas Bahá’u’lláh hath made the Center of the Covenant the Interpreter of His Word—a Covenant so firm and mighty that from the beginning of time until the present day no religious Dispensation hath produced its like.” The very completeness of the servitude with which ‘Abdu’l-Bahá promulgated the Faith of Bahá’u’lláh in East and West resulted at times in a confusion of belief concerning His station on the part of believers. Realizing the purity of the spirit animating His word and deed, surrounded by religious influences marking the breakdown of their traditional doctrines, a number of Bahá’ís felt that they honored ‘Abdu’l-Bahá by likening Him to a Manifestation, or hailing Him as the “return of Christ.” Nothing caused Him such intense grief as this failure to perceive that His capacity to serve Bahá’u’lláh proceeded from the purity of the mirror turned to the Sun of Truth, and not from the Sun itself.
