"In truth, that knowledge which belongeth unto Mine own Essence is such as none hath ever attained or will ever grasp, nor shall any heart be capable of bearing its weight."

"O Temple of Holiness! We, verily, have made Thine inmost heart the treasury of all the knowledge of past and future ages, and the dawning-place of Our own knowledge which We have ordained for the dwellers of earth and heaven, that all creation may partake of the outpourings of Thy grace and may attain, through the wonders of Thy knowledge, unto the recognition of God, the Exalted, the Powerful, the Great. In truth, that knowledge which belongeth unto Mine own Essence is such as none hath ever attained or will ever grasp, nor shall any heart be capable of bearing its weight. Were We to disclose but a single word of this knowledge, the hearts of all men would be filled with consternation, the foundations of all things would crumble into ruin, and the feet of even the wisest among men would be made to slip"
