Skimmed the article, remember reading it a long time ago... Many individuals on and off this site could argue against 'a case against the elves' point by point with contrasting opinions/anecdotes. The author was kind enough to leave the other fluff in there laced with logical gaps and hollow foundations, maybe as an invitation to a public dialogue?
just couldn't resist
WHAT DO THEY EAT?
This question makes me think of the plants&animals' respiration contributing to a symbiotic ecosystem. If we skip the "what are entities, what kinds, etc" questions, the next might be "do they eat" and if they do "what does 'eat' really mean for them".
IS IT US?
^paranoid. maybe they eat our bad energy because they are higher than connotations of good and bad. maybe they consume our ethereal excess that unbalances us. they don't eat my bills, what else don't they eat?.
I got eaten by a demon cat in a dream once, but it turned out to just be a portal-experience into another completely different phase of the dream.
HOW DO THEY EFFECT US
How do you choose to let them effect you? Reception is important: "Love and Gratitude" -antrocles
Using blanket terms like "us" is kind of a bad setup for the question. Time will tell, historians will have their stories. How can you use your experience to make the world that surrounds you a better place?
WHAT PURPOSE DO >they< HAVE FOR CONTACTING US
Do they have a purpose for contacting us? Aren't we the ones smoking dmt and contacting them? What's our purpose for contact? Why should it be different if we're both sets of living entities? ah, this makes me long for hyperspace.
CAN THEY BE TRUSTED AT ALL?
Thieves think everybody steals.
When I was with aya a few times a week some time ago, I got insight from entities that applied to conversations with other humans after the fact. Did I need to cite the entities as sources for this knowledge and get into the above discussions? No, but I did for a while until the over-thought happened that my body/brain/mind is my license here and now to share these insights as my own.
This of course requires an investigation of sound reasoning that builds the insight, which makes for great post-journey reflection. Usually it involves if/where the idea's been relayed before to find various sources/connections for the variety of human recipients that come around, though in my favorite instances it's a ground-up construction. Best of all the experience can then be shared with a wider audience (hooray!).
Expanding the intellect and isolating the I, all under the guise of sanity. Just beautiful.
