Blink ,many people have put there interpretation onto the tablets, but I 'm sure you will find,that these interpretations are based only on the perspective of the soul.
It is written so each at there own level can gain a corresponding knowledge.It is as it is,here are some extracts .
The keys of magic
Hark ye o man, to the wisdom of magic.
Hark the knowledge of powers forgotten.
Long,ago in the days of the first man,warfare began between darkness and light.
Man ,then as now,
Were filled with both darkness and light,
and while in some darkness hell sway,
in others light filled the soul.
Aye,age old in this warfare,
the eternal struggle between darkness and light,
fiercely is it fought all through the ages,
using strange powers hidden form man.
Adepts has there been filled with blackness,
Struggling always against the light,
but others there are who, filled with the brightness,
have ever conquered the darkness of the night,
Where e'er ye may be in all ages and plane,
surely,ye shall know of the battle with night.
Long ages ago,
The suns of the morning,
descended, found the world filled with night,
there in that past began the struggle,
the age old battle between darkness and light.
Many in the time were so filled with the darkness,
that only feebly flamed the light on the night.
Some they were, masters of the darkness, who sought to fill all with their darkness,
sought to draw others into there night
Fiercely withstood they, the masters of brightness,
fiercely fought they from the darkness of the night,sought ever to tighten the fetters,
the chains that bind men to the darkness of the night.
Used they always the dark magic,
brought into men by the power of darkness,
magic that enshrouded mans soul with darkness.
this is just a small peace from the tablets you can find then in full @
