there are a lot of small ways to practice my religion, just as in other religions. mainly i like to carry crystals around with me, i meditate often, and i work on my Book of Shadows- which isn't as edgy as it sounds. it's a journal to account for my spiritual journey, but it's just relaxing to decorate.
on the larger scale, i practice divination, although it's not something i do super regularly as it requires quite a lot of energy and set-up. i mostly read tarot cards, but i also cast runes and can read pendulums.
very occasionally i'll do spell work which i know sounds ridiculous to a lot of people but it's more like a ritual to set intention rather than using a wand to turn a frog into a rat or something like that.
i worship my patron goddess who is Sól, the norse goddess of the sun and i also worship Freyja, the norse lady. all of those things ^ contribute to my worship, so i usually ask Sól to guide me in a tarot session for example.
other forms of worship are offerings, and i really like crystals so i usually buy certain crystals to offer to my goddesses. many gods and goddesses in pagan worship have respective elements, herbs, crystals, etc. so i have a lot of amazonite because it correlates with Sól
and no, i do not believe in animal sacrifice. i think it's a bit outdated, but also unrealistic in a modern society. also i'm a vegetarian, LOL. i don't have anything against people who do take part in animal sacrifice as long as they're doing it legally and not putting others in danger by doing so. I don't see the difference in using say, a goat, in animal sacrifice, and killing that goat to eat. either way you're killing an animal.
