Knowledge

A divine Mine only can yield the gems of divine knowledge, and the fragrance of the mystic Flower can be inhaled only in the ideal Garden, and the lilies of ancient wisdom can blossom nowhere except in the city of a stainless heart. "In a rich soil, its plants spring forth abundantly by permission of its Lord, and in that soil which is bad, they spring forth but scantily."

Bahá’u’lláh, The Ki tab-i-Ian, p. 190

And if, confirmed by the Creator, the lover escapes from the claws of the eagle of love, he will enter THE VALLEY OF KNOWLEDGE and come out of doubt into certitude, and turn from the darkness of illusion to the guiding light of the fear of God. His inner eyes will open and he will privily converse with his Beloved; he will set ajar the gate of truth and piety, and shut the doors of vain imaginings.  He in this station is content with the decree of God, and seeth war as peace, and findeth in death the secrets of everlasting life. With inward and outward eyes he witnesseth the mysteries of resurrection in the realms of creation and the souls of men, and with a pure heart apprehendeth the divine wisdom in the endless Manifestations of God. In the ocean he findeth a drop, in a drop he beholdeth the secrets of the sea.

Bahá’u’lláh, The Seven Valleys, p. 11-12

But having weighed the testimony of God by the standard of their own knowledge, gleaned from the teachings of the leaders of their faith, and found it at variance with their limited understanding, they arose to perpetrate such unseemly acts.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 18

Fear God and God will give you knowledge.

Bahá’u’lláh, The Seven Valleys, p. 3

In this day the mysteries of this earth are unfolded and visible before the eyes, and the pages of swiftly appearing newspapers are indeed the mirror of the world; they display the doings and actions of the different nations; they both illustrate them and cause them to be heard. Newspapers are as a mirror which is endowed with hearing, sight and speech; they are a wonderful phenomenon and a great matter. But it behoveth the writers thereof to be sanctified from the prejudice of egotism and desire and to be adorned with the ornament of equity and justice; they must inquire into matters as much as possible, in order that they may be informed of the real facts, and commit the same to writing.

Bahá’u’lláh, Bahá’í World Faith, p. 171

Know thou of a truth that the seeker must, at the beginning of his quest for God, enter the Garden of Search. In this journey it behoveth the wayfarer to detach himself from all save God and to close his eyes to all that is in the heavens and on the earth. There must not linger in his heart either the hate or the love of any soul, to the extent that they would hinder him from attaining the habitation of the celestial Beauty. He must sanctify his soul from the veils of glory and refrain from boasting of such worldly vanities, outward knowledge, or other gifts as God may have bestowed upon him. He must search after the truth to the utmost of his ability and  exertion, that God may guide him in the paths of His favour and the ways of His mercy. For He, verily, is the best of helpers unto His servants. He saith, and He verily speaketh the truth: "Whoso maketh efforts for Us, in Our ways shall We assuredly guide him." And furthermore: "Fear God and God will give you knowledge."
