Hello xxtraminimal,
I have taken a look at this work you mentioned, the Revolution of Beelzebub. I think it is a crackpot concoction and a waste of your time. In previous posts we have recommended works to you and those may prove to be of greater lasting value.
http://sawzone.org/docs_eng/Revolution_Of_Beelzebub.pdfTo your specific question, the Tantric work that holds the answer is called the Vijnana Bhairava. It is about the practice of centering awareness to uncover the Divine because the Divine is everywhere and in everything. We do not see It because of our own false sense of limitations and thought-constructs. Any powerful emotion, even anger, can offer us a glimpse if we can catch hold of it.
Here are some exercise to practice. In doing these, try to be aware of the feelings and to tell yourself in your mind that these are the Divine Bliss. With practice you can learn to peel-away your own projections and thought-constructs to see and experience them as they are. Right now, you are not. This is something that time some work.

The delight experienced at the time of sexual union when the female energy is excited and when the absorption into her is completed, is similar to the spiritual bliss and that bliss is said to be that of the Self.

O Goddess, even in the absence of a woman there is a flood of delight by merely remembering the sexual joy experienced while kissing, embracing, pressing etc.

At the time of experiencing great bliss or the joy of seeing a friend or relative after a long time, one should meditate on the rising of this bliss and, while merging with it, one's mind will become one with it.

When one is filled with joy arising from the pleasure of eating and drinking, one should mediate on the state of fullness. There the great bliss will arise.

Wherever the mind finds satisfaction, let it be fixed there, for there itself the nature of supreme bliss will become manifest.

Fixing one's gaze without blinking on an external beautiful form, and making the mind support-less in a short time, one will attain to Lord Shiva.
