Message in a bottle

[anagogy]

Sometime I would have a period of peace, lasting a few months. I almost forget about it all.

But then it all comes back, with a single experience, always that same feeling of dread and evil.

If you don't clean your dwelling regularly in certain places, mold will grow in damp/moist, dark places.

Negative astral entity attachments are, in many interesting ways, like black mold. They grow over time in the right conditions. And just like black mold, there is no one time cleaning that will get rid of it forever, usually. The domicile must regularly cleansed, which leads to more of a resistance to such things growing.

Formulate your own banishing ritual, and say it as prayer, blessing, every night before you go to bed. Firmly claim custodianship of your dwelling and strongly AFFIRM that only positive beings are welcome in your space.

You can elaborate on the ritual if you like, or use one someone else has created, but repetition is the key. Love and light should be the building blocks of whatever ritual/blessing/prayer you create. I would advise making it short enough that you could easily repeat 3 or more times in a row without it being too much of a chore (if you only do it once, what separates a magical act from a normal act?). I would end the ritual by visualizing love imbued light radiating and charging every particle, nook, and cranny of your dwelling (including yourself). As you visualize that white light, say mentally or physically, emphatically and strongly: "I purify and sanctify this dwelling in the love and light of the one infinite creator, for the law is one."

This is just a suggestion. Once you create that, the more you repeat it, the stronger it will become. Everything is a muscle. A regularly cleaned domicile will not provide the conditions for the so called metaphysical mold to spread or grow.
