I have over hundred of tea light candle at home, but I did have concern with our respiratory system and health issues if we lit up candles quite often.
Anyone know if candle is the necessary offering? Seems most of the spirit like candle very much. Any substitution for offering?
I can only speak from my experience working with my spirit family.
Besides candles and incense, they seem to like booster beads and moon charged stones. I also have one of those charged altar tiles sold in the Blujay shop.
Some enjoy moon water. I have one that would take chocolate.
I also practice energy work, meditation, and astral travel with them, they seem to like that too.
