About prayers
I'll chime in on this, I burn my about prayers while doing rituals, but i have my alter set up is in the basement, and I use fans to draw away the smoke from burning prayers, and incense.
I used to use a box fan a 12X 12 for the basement window but now i made a math room fan kit for the basement
You may be able to use a fan to draw the smoke, incense out of your space where you are doing rituals at, it a loud fan will also hide chanting, you always Say you like to sleep or have the fan on because your too warm LOL and just burn the prayers in front of the fan it's self
Hail Satan!
