As the original poster posits... 'you cannot run high voltage creative energy through frayed, fragile, and un rectified internal wiring systems' (paraphrasing words). The force spoken of in that original post of Nuit and Hadit are precisely the energetic points Embodied within the work in the higher grades (later course 3 and very directly in course 4) While we are not Thelemite, there are certain energetic points we work with and draw from that are a part of current 93. Our current is that of 326 (CCCXXVI)
Digression aside (you're more then welcome to enquire further) the focus lies in the working spoken about with the link shared. In our standard human paradigm, creational force is often... Not misused... It is human to desire pleasure and feel connection... But it's use is not as guided and focused into the true power behind... or rather within... that it emanates from, which allows MUCH to come forth as a result.
The 'exercise' posted is powerful and a for use as a sole practice for those who wish to experiment. Again, the warning is there for a good reason... This speaks to the paradigm mentioned above. When creational force is excited in a system that's not cleared, clean, and non egoic; the outcome OFTEN spews forth in; sadness post work, nausea, dizziness, high emotional volatility, internal conflict, and energetic storms....
Do as you will with the above... After all... Magick is the Art and Science of causing change to consciousness... I do highly encourage you to read about it... The truth is most definitely there... Creational force is powerful and it is a space that should be realigned with it's true purpose... with the true I.
