The sciences of today are bridges to reality; if then they lead not to reality, naught remains but fruitless illusion. By the one true God! If learning be not a means of access to Him, the Most Manifest, it is nothing but evident loss. It is incumbent upon thee to acquire the various branches of knowledge, and to turn thy face toward the beauty of the Manifest Beauty, that thou mayest be a sign of saving guidance amongst the peoples of the world, and a focal centre of understanding in this sphere from which the wise and their wisdom are shut out, except for whoso setteth foot in the Kingdom of Lights and becometh informed of the veiled and hidden mystery, the well-guarded secret. (“Selections from the Writings of ‘Abdu’l-Bahá” [rev. ed.], (Haifa: Bahá’í World Centre, 1982), Sec. 72, p. 110) [28] “29: Man is in the highest degree of materiality, and at the beginning of...” Man is in the highest degree of materiality, and at the beginning of spirituality—that is to say, he is the end of imperfection and the beginning of perfection. He is at the last degree of darkness, and at the beginning of light; that is why it has been said that the condition of man is the end of the night and the beginning of day, meaning that he is the sum of all the degrees of imperfection, and that he possesses the degrees of perfection.

If he comes under the shadow of the True Educator and is rightly trained, he becomes the essence of essences, the light of lights, the spirit of spirits; he becomes the centre of the divine appearances, the source of spiritual qualities, the rising-place of heavenly lights, and the receptacle of divine inspirations. If he is deprived of this education, he becomes the manifestation of satanic qualities, the sum of animal vices, and the source of all dark conditions. The reason of the mission of the Prophets is to educate men, so that this piece of coal may become a diamond, and this fruitless tree may be engrafted and yield the sweetest, most delicious fruits. When man reaches the noblest state in the world of humanity, then he can make further progress in the conditions of perfection, but not in state; for such states are limited, but the divine perfections are endless.
