How great the multitude of truths which the garment of words can never contain! How vast the number of such verities as no expression can adequately describe, whose significance can never be unfolded, and to which not even the remotest allusions can be made! How manifold are the truths which must remain unuttered until the appointed time is come! Even as it hath been said: "Not everything that a man knoweth can be disclosed, nor can everything that he can disclose be regarded as timely, nor can every timely utterance be considered as suited to the capacity those who hear it."
Of these truths some can be disclosed only to the extent of the capacity of the repositories of the light of Our knowledge, and the recipients of Our hidden grace. We beseech God to strengthen thee with His power, and enable thee to recognize Him Who is the Source of all knowledge, that thou mayest detach thyself from all human learning, for, "what would it profit any man to strive after learning when he hath already found and recognized Him Who is the Object of all knowledge?" Cleave to the Root of Knowledge, and to Him Who is the Fountain thereof, that thou mayest find thyself independent of all who claim to be well versed in human learning, and whose claim no clear proof, nor the testimony of any enlightening book, can support.
