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 … 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)
