:The Four Powers of the Magus:

The Four Powers of the Magus are the personal attributes traditionally necessary and required for the successful use and practice of magic.
These are - To Know, To Dare, To Will, and To Be Silent.

Without these four attributes combined, the individual will never be successful in magic. The reasoning is quite simple; none of the attributes mentioned are enough in themselves, as all four attributes must be present to balance each other out. For instance:

   To Know ~ Knowledge is no good, without the will and audacity to see magick done.
   To Dare ~ Audacity is no good, without the knowledge and will to see magick done.
   To Will ~ Will power is no good, without the knowledge and audacity to see magick done.
   To Be Silent ~ What good are the above, without the discretion to remain silent until the magick is done? To reveal your magick before it is done, dissipates its power and effectiveness.

So, anyone aspiring to use magick needs a knowledge of what they are doing, the audacity to use it, the will power to control it, and the discretion to remain silent till the work is done.
