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 in the estimation of the divine philosophers this proof and assurance is not reliable; nay, rather, they deem the standard of the senses to be false because it is imperfect. Sight, for instance, is one of the most important of the senses, yet it is subject to many aberrations and inaccuracies. The eye sees the mirage as a body of water; it regards images in the mirror as realities when they are but reflections. A man sailing upon the river imagines that objects upon the shore are moving, whereas he is in motion, and they are stationary. To the eye the earth appears fixed, while the sun and stars revolve about it. As a matter of fact, the heavenly orbs are stationary, and the earth is turning upon its axis. The colossal suns, planets and constellations which shine in the heavens appear small, nay, infinitesimal to human vision, whereas in reality they are vastly greater than the earth in dimension and volume. A whirling spark appears to the sight as a circle of fire. There are numberless instances of this kind which show the error and inaccuracy of the senses. Therefore, the divine philosophers have considered this standard of judgment to be defective and unreliable.

Even enemies bore witness to his high-mindedness and his spiritual qualities, and they would way: “There is none to compare with this man for his words and acts, his righteousness, trustworthiness, and strong faith; in all things he is unique; what a pity that he is a Bahá’í!” That is: “What a pity that he is not as we are, perverse, uncaring, committing sins, engrossed in sensuality, the creatures of our passions!” Gracious God! They saw with their own eyes that the moment he learned of the Faith he was transformed, he was severed from the world, he began to emit rays from the Sun of Truth; and still, they failed to profit by the example he set.
(‘Abdu’l-Bahá, Memorials of the Faithful, p. 127)
If Thou wishest a discerning eye and seekest for a hearing ear, set thou aside that which thou hast heard from fathers and ancestors, for such things are imitation—and then seek for the truth with the utmost attention until the divine confirmation may reach thee ant the matter may be properly disclosed unto thee.
(Bahá’u’lláh, Bahá’í World Faith, p. 387)
Only through the honor of entering His presence, many souls became confirmed believers; they had no need of other proofs. Even those people who rejected and hated Him bitterly, when they had met Him, would testify to the grandeur of Bahá’u’lláh, saying, “This is a magnificent man, but what a pity that he makes such a claim! Otherwise, all that he says is acceptable.
(‘Abdu’l-Bahá, Some Answered Questions, p. 36)
The light of truth hath made thine eyes to see, the voice of God hath made thine ears to hear and the lights emanating from the beauty of the Light of the World both made thine heart attracted and astonished. I hope that thou wilt cut thyself from all that is in this world; wilt sever thyself from all desires of this transitory world; wilt attach thy heart entirely to the light of truth and wilt, at all times, rise in the service of truth in the rose-garden of God.
