Well from my experience, doing rituals like that in the astral happens instantaneously, like you get rid of the nitty gritty details, it’s hard to explain, but both work, the astral is a relative space, so anything works as long as you say it does, especially if it’s your own temple
So lets say i want to work on image/poppet in the astral… I have to prepare it like i would do, charging it with astral magick and going back to it many times a day to keep the magick going?
