No need - when I am writing I am always silent .
I was not claiming that knowledge comes from the GD teachings but the 'extracurricular' recommended . And so , any simple reference to it , should, for anyone that has done the work , refer back to a NUMBER OF teachings and practices you were supposed to develop .
In the system I was involved in, Thelema or any system using it never promised to be a world library of all knowledge , a lot of it is curriculum and reference to works you are supposed to be studying and practices you are supposed to be developing . And I notice that people never that never approached it that way either failed, faded , thought the system useless or complained and thought they were 'above it all ' .
For example ; I might tell a martial arts student , at this stage they should, or it would be very important , or even in some cases essential that they take up A yoga practice .... I am not going to teach them yoga ... but I might suggest THEY find a system and practice it .
