"Only when the lamp of search, of earnest striving, of longing desire, of passionate devotion...will...the lights of knowledge and certitude envelop his being."

"Only when the lamp of search, of earnest striving, of longing desire, of passionate devotion, of fervid love, of rapture, and ecstasy, is kindled within the seeker’s heart, and the breeze of His loving-kindness is wafted upon his soul, will the darkness of error be dispelled, the mists of doubts and misgivings be dissipated, and the lights of knowledge and certitude envelop his being. At that hour will the Mystic Herald, bearing the joyful tidings of the Spirit, shine forth from the City of God resplendent as the morn, and, through the trumpet-blast of knowledge, will awaken the heart, the soul, and the spirit from the slumber of heedlessness. Then will the manifold favors and outpouring grace of the holy and everlasting Spirit confer such new life upon the seeker that he will find himself endowed with a new eye, a new ear, a new heart, and a new mind. He will contemplate the manifest signs of the universe, and will penetrate the hidden mysteries of the soul. Gazing with the eye of God, he will perceive within every atom a door that leadeth him to the stations of absolute certitude. He will discover in all things the mysteries of Divine Revelation, and the evidences of an everlasting Manifestation."

"Knowledge of the Manifestations of God is the knowledge of God..."

Shrine of the Báb and surrounding gardens

"The knowledge of the reality of the Divinity is in no wise possible, but the knowledge of the Manifestations of God is the knowledge of God, for the bounties, splendours, and attributes of God are manifest in Them. Thus, whoso attains to the knowledge of the Manifestations of God attains to the knowledge of God, and whoso remains heedless of Them remains bereft of that knowledge. It is therefore clearly established that the Holy Manifestations are the focal centres of the heavenly bounties, signs, and perfections. Blessed are those who receive the light of divine bounties from those luminous Daysprings!"

"Material science is the investigation of natural phenomena; divine science is the discovery and realization of spiritual verities."

Mansion of Mazra'ih

"Scientific knowledge is the highest attainment upon the human plane, for science is the discoverer of realities. It is of two kinds: material and spiritual. Material science is the investigation of natural phenomena; divine science is the discovery and realization of spiritual verities. The world of humanity must acquire both. A bird has two wings; it cannot fly with one. Material and spiritual science are the two wings of human uplift and attainment. Both are necessary—one the natural, the other supernatural; one material, the other divine. By the divine we mean the discovery of the mysteries of God, the comprehension of spiritual realities, the wisdom of God, inner significances of the heavenly religions and foundation of the law."
