As Im for the most part working with norse gods, can I also work with other deities from other religion? I dont want to upset any deities, so I was wondering if they will be upset for working with different deities?
Yes, but there are a number of things to consider.
If you're a Heathen [Norse Pagan] you should focus on that religion and strengthening your bonds with those Gods. Not saying you can't be a Heathen who also works with Neptune, I'm just saying there are a plethora of Norse Gods who can guide you just as well as Gods from other pantheons. Gods are also not Pokemon, you don't collect them. Gods are like friends, some you'll be closer with than others, but you need to spend time with each person, get to know them, and form a bond. You don't have to be best friends with every Norse God, but just because you met Loki once in a meditation, doesn't mean they're your BFF and are hanging around 24/7 waiting to go on adventures with you. Think of it more like seeing someone in the hallway between classes. Just because you waved at them and they waved back, doesn't mean you have something special. It just means they acknowledged your greeting.
However, if you're drawn to a deity from another pantheon, that doesn't mean you can't work with them. I would advise you to consider a few things, like how much time/energy/effort you can put into a relationship with a God [some people have a strong bond with 5 or more deities, while others only work with 1. While I've worked with many deities over the years, the max I can handle at a time was 4, and even then I was more focused on 2 of them. Finding the balance can be difficult, especially at first. Currently, I work with 2 and occasionally say hi to a third] You should also consider the deities' mythology and if the cultures were historically at war. Loki and Dionysus could definitely get along, but I wouldn't be so sure about Hela and Bast. The final point to consider is if the deity is from a closed religion. There are plenty of closed practices [either due to culture or initiation] so do your research and see what those who work with the deity say. I've heard plenty of "but I feel drawn to Kali!" [or other specific deities] and my response is 1. is she calling to you, or do you just think she's cool? and 2. If she is calling to you, how are you sure it's not to tempt you off a cliff? Deities can indeed lie. It's a very real possibility a deity from a closed practice enters your life to throw it into turmoil because you need to be taught a lesson. [usually, it's the result of white people going "I want to practice this PoC religion, I don't care if you say it's closed, you're just a gatekeeping hater" and then Papa Legba or someone similar appears and is all "hey, come with me" and the next thing this person knows their life has been rocked to its core]
I don't mean to scare you out of deity work, I'm saying you need to differentiate between "this is a deity calling to me" and "this deity is cool and I want to work with them" which can be difficult when you're new. When I began my practice, I was obsessed with Egyptology [it's been a passion of mine since childhood] and every two weeks, I'll be contacting a different Egyptian deity to work with but not putting in any effort beyond "this is so cool! I'm working with Sobek! I'm having a bla- Wait, is that Osirus?!" So I understand the excitement, but you should get a meditation and journal routine started first, just so that you can check in with yourself and make sure this is a deity calling to you and not a fade. It's been 20 years since I began my journey. I've worked with and without deities. And what I've learned is quality over quantity. Reflect on what you desire. Is it wisdom? Confidence? Love? Maybe your favourite animal's a wolf, or you do axe throwing as a hobby. Research deities associated with your interests [start with Norse, or your ancestor's deities and then branch out] research each one and sit with them. Reflect on what you learned about them, and how you feel about them. It's frustrating to say "you'll know" but trust me, it'll be a lightbulb moment when you find a deity you wish to work with because they're calling to you and not because "Thor's cool."
Okej, Im a norse pagan for a reason, and I will most likely only work with Norse gods. The reason I was asking this was if I meet another deity as Im Astrial Project that is outside of the norse gods, I dont want to be rude to that deity and say I only work with Norse gods.
Lets say I meet my guardian angel and Angels is not Pagan, I dont want to blindly say, Dont talk to me. I guess Im worried if this happens, norse gods will think Im abandoned them, which Im not and I will never do. I hope they understand just because I talk to someone does not mean I will work with them.
If you come across a spiritual being on your journey, you can be polite [you should be somewhat respectful towards them] While angels are Christian in nature, Pagans do work with them [Christian Witches come to mind] angels, demons, dragons, faeries, jinns, spirits, and many more are beings you could come across on your path, just say hi and keep going. There are times when a trickster spirit will pretend to be a deity, so you should do some divination and ask questions to be certain it is who they say they are. And on rare occasions, a deity you don't wish to work with will reach out to you. You can say no. If this happens, basically say "thank you, but I don't wish to work with you" [you can add "at this time" if you want to keep the door open. You can also give an explanation, but it can be as simple as saying "no"] I've said no to deities before, and the only one who didn't take no for an answer was a deity I dedicated myself to in my teens. It all worked out, but the moral of that tale is always think things through. [I dedicated myself to them at 17 for a really dumb exchange] It worked out in the long run because we have an amazing relationship now, but dedications aren't something you should take lightly. Just because you think a deity is cool, doesn't mean they're your matron/patron deity and you should dedicate yourself. Again, I've worked with dozens of deities and only dedicated myself to 1. I'm debating dedicating myself to another deity, but unlike the first one, I've worked with them for 2 years at this point [when I dedicated myself to my deity in my teens, it was after a week and I basically went "okay, you get me X and I'll dedicate myself to you"] I tell you this as a warning, but also a reminder everyone was new and everyone has done silly things in their craft.
From my personal experience in working with the Norse it is not uncommon for them to pick up a person as a follower and "introduce" them to other deities from different cultures. It is also not uncommon for them to suggest a person "convert" to another religion and pantheon.
Our gods have a different understanding of the world, humans and our worship of them. They don't seem (in my experience) to have issue with sharing us and our worship.
Many of the Norse practitioners I know of say that they started working with Odin only to have him deliver them to another god or goddess and tell the person to follow that one.
