What "oppression" is greater than that which hath been recounted? What "oppression" is more grievous than that a soul seeking the truth, and wishing to attain unto the knowledge of God, should know not where to go for it and from whom to seek it? For opinions have sorely differed, and the ways unto the attainment of God have multiplied. This "oppression" is the essential feature of every Revelation. Unless it cometh to pass, the Sun of Truth will not be made manifest. For the break of the morn of divine guidance must needs follow the darkness of the night of error. (Baha'u'llah: The Kitab-i-Iqan, page 31)
