=Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry by Pike=
>These Degrees are also intended to teach more than morals. The symbols and ceremonies of Masonry have more than one meaning. They rather conceal than disclose the Truth. They hint it only, at least; and their varied meanings are only to be discovered by reflection and study. Truth is not only symbolized by Light, but as the ray of light is separable into rays of different colors, so is truth separable into kinds.
> The Blue Degrees are but the outer court or portico of the Temple. Part of the symbols are displayed there to the Initiate, but he is intentionally misled by false interpretations. It is not intended that he shall understand them; but it is intended that he shall imagine he understands them. Their true explication is reserved for the Adepts, the Princes of Masonry. The whole body of the Royal and Sacerdotal Art was hidden so carefully, centuries since, in the High Degrees, as that it is even yet impossible to solve many of the enigmas which they contain. It is well enough for the mass of those called Masons, to imagine that all is contained in the Blue Degrees; and whose attempts to undeceive them will labor in vain, and without any true reward violate his obligations as an Adept. Masonry is the veritable Sphinx, buried to the head in the sands heaped round it by the ages.
