Dear JMG, I'm 50 years old and starting my studies in the occult. I have some health problems like high blood pressure and arrhythmia (atrial fibrillation) but both are controlled by medication. I would like to know if the study and practice of exercises like The Middle Pillar, Lessing Banishing Pentagram, Sphere of Protection or similar can bring any complications or worsen these health issues.

Kind Regards.
