In the book Stolen Legacy by George G.M. James the following is found on page 25. Here is explained the ethical system known as the Egyptian Mystery School.
In the Egyptian Mysteries the Neophyte was required to manifest the following soul attributes:
(1) Control of thought and
(2) Control of action, the combination of which, Plato called Justice (i.e., the unswerving righteousness of thought and action).
(3) Steadfastness of purpose, which was equivalent to Fortitude.
(4) Identity with spiritual life or the higher ideals, which was equivalent to Temperance an attribute attained when the individual had gained conquest over the passional nature.
(5) Evidence of having a mission in life and
(6) Evidence of a call to spiritual Orders or the Priesthood in the Mysteries: the combination of which was equivalent to Prudence or a deep insight and graveness that befitted the faculty of Seership.
Other requirements in the ethical system of the Egyptian Mysteries were:
(7) Freedom from resentment, when under the experience of persecution and wrong. This was known as courage.
(8) Confidence in the power of the master (as Teacher), and
(9) Confidence in one’s own ability to learn; both attributes being known as Fidelity.
(10) Readiness or preparedness for initiation. There has always been this principle of the ancient mysteries of Egypt: “When the pupil is ready, then the master will appear”. This was equivalent to a condition of efficiency at all times for less than this pointed to a weakness. It is now quite clear that Plato drew the four Cardinal virtues from the Egyptian ten; also that Greek philosophy is the offspring of the Egyptian Mystery System.
