The dedication isn't about, 'do the dedication and all your problems are solved.' You won't achieve Spiritual change or build a strong relationship with Satan over night after doing just one ritual. Yes you begin to form a bond with Satan through the Dedication ritual, if done for the right reasons. But Spiritual Satanism is something that needs to be worked at every day. Not an 'overnight cure'.
Work on Power Meditations, empowering your soul and learning all you can. Read the JoS over and over till you can recite it with your eyes closed. There is so much info there.
You wont experiance anything sitting around waiting for it. It is something that has to be lunged into and taken seriously. You must do the work required to experiance True Satanism. You cannot sit around waiting for it to come to you.
