Always essential:
In terms of atmosphere, in the past I've used colored lights and black lights for extra drama. I've also used binaural beats, Gregorian chants with binaural beats, and meditation videos.
- Candle, how many and the color depend on the operation, but at least one white candle
- Small fire extinguisher, handy but hidden; it's there if I need it, although I'm very careful with fire
- Electric candle in place of the real candle if I expect to be doing something like going into a long trance in the Earth position, although I haven't done that in years
- Incense
- Main altar and an appropriate altar cloth
- Robe & ring
- Whatever else is required for the operation
