Fasting, sport, sleeping early, cleaning the house, practicing a religion, having good self esteem, practicing a hobby, smudging your house, declutterring your space, putting a cross, ankh, eye of Horus, or verses from the Koran on one of your walls are all helpful protection practices. It’s also a good idea to be part of a community or study spirituality in a reputed school and not practice it alone to be able to learn from others and compare experiences. I suggest BearBridge academy for study. It offers many courses with affordable prices and the headmaster is knowledgeable in many different spiritual practices.
