“To attain the Sanctum Regnum, in other words, the knowledge & power of the Magi, there are four indispensable conditions: an intelligence enlightened by study, a courage that nothing can shake, a will that cannot be broken & a discretion that nothing can corrupt or pollute.
Knowing, daring, willing, keeping silent are the four words of the Magus, inscribed on the four symbolic forms of the Sphinx.
To dare we must know; to want, we must dare; we must will to obtain the empire & to reign we must keep silence” Eliphas Levi
