Bahá’í World Faith—Selected Writings of Bahá’u’lláh and ‘Abdu’l-Bahá (‘Abdu’l-Bahá’s Section Only)

Know thou, that letter sent to thee by me, was only because of my perfect love for thee and my pity upon thee, for I had the desire that the fragrance of the Holy Spirit, which hath perfumed all regions and imbued the entire body of the world with the Spirit of Life, should pass over thee and abide with thee. Notwithstanding the high position it occupieth, still, with an eloquent tongue, through which the Spirit moveth, hearts are attracted and bosoms burn, it speaketh to the pure hearts and to the good and righteous souls in every spot of the earth. This is the powerful Spirit, the dazzling light, the brilliant star and the overwhelming and universal abundance. And, from its traces, spread and divulged everywhere, thou wilt know and realize its influence and comprehend its radiance. I ask God to expose thee to its fragrance, move thee by its breeze, enkindle thee by its coals of fire and illuminate thee 369 by its brightness. Turn thyself wholly to it—thus thou shalt be enabled to ascertain its influence and power, the strength of its life and the greatness of its confirmation. Verily, I say unto thee, that if for the appearance of that Divine Essence thou desirest to have a definite proof, an indisputable testimony and a strong, convincing evidence, thou must prepare thyself to make thy heart empty and thine eye ready to look only toward the Kingdom of God. Then, at that time, the radiance of that widespread effulgence will descend upon thee successively, and that motion rendered thee by the Holy Spirit will make thee dispense with any other strong evidence that leadeth to the appearance of this Light, because the greatest and strongest proof for showing the abundance of the Spirit to the bodies is the very appearance of its power and influence in those bodies.
