Others say that you absolutely need to have this, that, or the other as a ritual sacrifice or offering, like sulfur for a fire elemental. Others still say that it’s a good idea to have stuff like that on hand, but some spirits will want something physical and some won’t. Of course, one can always argue the notion of equivalent exchange from the anime, Fullmetal Alchemist, and while this is an anime, it’s basic precept still holds worth. However, perhaps this is just a sacrifice or offering for our own good, like has been said that the scent of a particular incense bringing about subconscious parts of ourselves that make particular invocations or other rituals easier for us, whereas the spirits couldn’t care less.I can't say what entities want or not. I would doubt they'd want anything because they are spiritual beings and you have nothing to offer them other than working with them, acknowledging them, allowing them to share knowledge with you etc.
I mean, like, what can you offer a god for instance - what's the point if you need to offer something. You must understand these beings are above all that. We humans think that they must be like us - in my experience with the 50 Names they are not like us i.e. they're not asking for some money, or gold etc. They're happy that you work with them.
Also, it could very well be that some spirits, like fire elementals, are truly drawn to a physical substance we’ve brought out to entice them with, merely for its properties as a rather fiery substance. Certain incenses, like Mugwort as was and is used in China for summoning, can and probably do have effects like this. But that doesn’t necessarily explain why some people think (and probably also have good reason to believe) that nothing is for free, and why others can perform all rituals in their heads with absolutely no physical offering and get the Maker itself to lend its energy.
I think that the expansion of the human consciousness and the evolvement of our spiritual bodies is the goal of most spirits in orbit of our spatial and spiritual realm. I think that we, in our little abode floating through the heavens, is something like a project. To elaborate is an explanation of where I got this idea:
The College of Metaphysics and branching Schools of’ have a method of accessing the akashic records much like Edgar Cayce did for his healings and readings. They have a reporter, who goes into the trance to read the records, and a conductor who the reporter is trained to work with, that can ask questions to generally guide the query. They have many uses for these readings but one of them, for at least 30 years now, has been to record information taken from lifetimes during what they call the Atlantean period. Now, I don’t even know my own self whether Atlantis existed or not, as there are so many credible ideas that prove both that it did and did not. However, what they got out of those peerings into the records was information on lives both human and not, of people who (as the reporter depicts) had specific goals such as to find out just how much oxygen it takes to support “such and such” sized entity, how much of what food to eat, how to make the planet grow such foods naturally to support higher organisms, what range of hormones it takes to run this or that body properly, and so on.
Millions of years of this produced a generally humanoid body with generally humanoid goals, eventually leading to the magnificent crystal technologies and civilization which Plato described. That is not to say that humans were the overall goal and most wonderful thing to come out of it, simply that it did happen, and we happen to be human, so why not use that as a reference. This is all entailed in a book titled Remembering Atlantis which goes on to summarize that the development of complex thoughts and emotions, as well as connections to the akashic records and astral planes themselves, were experimented with and is why, today, we can do what we do with our minds. Their take is that the peoples from the Pleiades (advanced and generally like angels to us), Sirius (sister spirits, so to speak), and Alpha Centauri (advanced but still physical species) all have their part and interests in developing us, as well as now ascended masters and other enlightened human spirits.
Again, this may all be drivel, and if you choose to see it that way, so be it. Like I said, even I who’ve read into it awhile have trouble with some of the suppositions. But at least take away from this concept one notion: that perhaps the master animal spirits, great citizens of the cosmos, and ascended masters of our own people have an interest not only in making bargains with us, but in seeing us reach for our rightful place among them. Maybe this is why they don’t care whether we have something to offer them except experiences, sweat and the jovial delight it brings them to see us continuously trip over our own psyche.
