The Four Powers of the Magus (aka Witch's Pyramid) are the personal attributes traditionally necessary and required for the successful use and practice of magick. These are - To Know, To Dare, To Will, and To Be Silent. Without these four attributes combined, the individual will never be successful in magick. Each represents a quarter of the foundation of the Power of the Magus.
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.
There is a fifth power sometimes noted - To Keep Faith, which is to believe in yourself, honor the Gods and keep the Laws.
