Dimensional Magic?

I'm talking about opening a hole into a dimension to talk or travel through it. Bending sounds like it should work too, lots of legends about a gateway where there are two places in the same place and that can transport you between them (Might just be fiction, not sure)

Oh. Well I'm not talking about that.

I found this of interest to me and I believe I can offer a different perspective but to understand you need three things.

First you need to realize that there is no limit of energy our spirits can use.

Second the knowledge that infinite is much much more than our minds can handle if we choose to keep them tethered to our physical plane.

And Three the understanding that there are no other realms or times and that the entirety of the cosmos exists and happens all at once and in the same place.

And so a question I must ask of you what do you seek to gain.

Side - assuming you're discussing ceremonial magic quite ironically the coven/group you're looking for is Higher Magicks. )

Hope this helped.

kalimanus almost hit the nail on the head

but he talked about bending reality toward us
thats not really how it works

you have to consider that we are beings of the universe
we are so used to thinking in physical terms that we would bend a metal bar to our will, iits just not the case with this stuff

how do i best explain this...
we as spiritual beings are the culmination of our experiences in our current life and past ones but we are a part of the universe in multiple planes wether we are conciously aware of it or not
the universe is experiencing itself through us, when you start to understand this, you dont bend reality to your will
your will bends you around reality, think of the universe wanting to go and visit one of its siblings
well the whole universe can't go, so we go for it.

I'd like to take a scientific standpoint for a second, mostly because I believe both Magick and science are intertwined. There is a theoretical instance called a wormhole. Wormholes are connetion point between either two planes of existence, referred to as intra-dimensional, or between two points on the same plane, called inter-dimensional. The reason this is able to happen is using black and white holes, black holes are comprised of incredibly tightly packed matter, which gives it incredible gravitational pull, so much so that light can't even escape it's pull. This is the only known way to travel between planes and already it proves impossible as you'd need the entire mass of Jupiter in order to form a black hoe that's a meter in diameter, it also wouldn't be there for long as black holes are very unstable. Then we come to white holes, the theoretical exits of wormholes, these have intense reverse gravity (The best explanation I found is that if you were to push a white hole, it would move towards you) because of the strange nature, you would need exotic matter, which is highly dangerous and theoretically impossible to create. You would also need a black hole to form in the correct position on our plane as a white hole of the other plane. Therefore, intra-dimensional travel is highly unlikely and could destroy our own universe. As I said before, trying to pass through planes of existence would require ripping a hole in the fabric of our reality, though I do agree with bending planes closer, though I don't know how hard it is to push hyperspace.

it sounds like the core of the disconnect going on here is indeed in the assumed methods of connecting with alternative dimensional spaces. it seems like people are assuming through physical means like generating a physically usable portal to step sideways and disappear 'here' to reappear ' somewhere else'. And in stating that is currently an impossibility, that is correct. Science has not yet progressed far enough to make that feasible.

However, others are assuming that you are referring to a spiritual or energetic connection. Such as channeling energy or astral travel. In which case they too are also correct. it is possible to shift your consciousness and awareness towards other planes of existence. Practitioners do it all the time. Connecting to the higher self, connecting with a Deity and their energies, Calling on the energy of the elements, Channeling healing energy through higher vibratory planes, and so on are all possible through esoteric principles and exercises.

So, both parties are right within their own perspectives.

As far as if there are any covens dedicated to this sort of practice, Like others have said who have been around longer than myself, Not that I am aware of. but not to worry it is not for any specific reason like cost or politics. more because one has not been necessary. because it is used so globally, it is safe to say that such ideas exist in every coven through one method or another. It isn't really something specialized in because it is a component of many practices. ...it would be similar to asking if there is a coven dedicated solely to circles and runes. it is prevalent enough to be utilized in many places and many ways, but the technique itself is more of a general principle than a possible core of any single practice.
