Sorcoress Cagliostro Blood Sorcery questions

I have been trying to work through the blood magick vols 1 and 2. For some reason I can’t get some things to ‘lock in’; and cannot get her or anyone associated with her to respond at all to answer some questions.
Is there any one here who uses her techniques and can maybe help me out with how to get these principles in operation ?

I would really appreciate it.
Thanks
