To me the Abramelin ritual is 'wack-a-doodle' . The recent film out about it caused a bit of discussion, which I took part in ( elsewhere) .
It appears to be some type of masked Judaism mixed with this and that , resulting in a ritual where ' you spend a lot of time to get pure and holy so you can force demons to let you see dancing maidens .
WTF that has to do with K&C of HGA ? wait for it ..... it is said it is done as a demonstration to show the practitioner has risen above being affected by such things and merely appreciates the artistic value
In my experience there is no one rite to do this ; it is either something a person has or is born with or something they found and / or developed after
various processes and experiences .
Also I advise not to get too hung up on the concept of HGA .... modify and combine it with concepts like 'tutelary spirit ' , ' Fraveshi and khvarenah' in Zoroastrianism , 'Daemon' / 'Genius' in ancient Greek .
Without this contact and guidance it is all but impossible to achieve Eudamonia !
