O My brother! When a true seeker determineth to take the step of search in the path leading unto the knowledge of the Ancient of Days, he must, before all else, cleanse his heart, which is the seat of the revelation of the inner mysteries of God, from the obscuring dust of all acquired knowledge, and the allusions of the embodiments of satanic fancy. He must purge his breast, which is the sanctuary of the abiding love of the Beloved, of every defilement, and sanctify his soul from all that pertaineth to water and clay, from all shadowy and ephemeral attachments. He must so cleanse his heart that no remnant of either love or hate may linger therein, lest that love blindly incline him to error, or that hate repel him away from the truth. Even as thou dost witness in this Day how most of the people, because of such love and hate, are bereft of the immortal Face, have strayed far from the Embodiments of the Divine mysteries, and, shepherdless, are roaming through the wilderness of oblivion and error. (Baha'u'llah, Gleanings from the Writings of Baha'u'llah)
