I wonder if its possible to meet all kinds of spirit & entity in the astral. Like those spirits & entities which doesn't belongs to the astral realm such as Flectere, merman, mermaid, elementals, Unicorn, satyrs, nymphos etc. Is the spiritual realm very different than astral realm. Can human enter spiritual realm by any mean or AP is enough to enter that realm? Is the astral realm doorway to all the realms? 1tk

Answer in order of questions:
- Yes,
- I'm not sure, but I think not by much,
- AP, not sure what you mean by "any" means,
- And sort of, with astral projection, you can go many places on the astral realm, yes.

Although I'm not sure what you mean by not belonging to the astral realm. There are most definitely merpeople, elementals, unicorns, nymphos, etc, on the astral plane.
So I'm not quite sure what you mean by that.

I astral project myself, and have met very entities and spirits, of a wide variety (although very few in comparison to other's adventures I'm sure) so I am sure it's very possible to meet a lot of things out there, astrally.

By not belonging to astral realm I mean their origin is not from astral realm. As it seems they cant walk over all the realms as shown in CH encyclopedia unlike angels & some other spirits & entities. Btw, thanks for your reply.

Well CH's info is very broad and somewhat inaccurate there. Cause there are nymphos, mermaids, and so forth, in the astral realm. I've met them myself personally as well.
And yes they can transverse the planes, if they learn. It's surprising what you can find when you look.

The encyclopedia hasn't been updated in while, so I would use it as a rough guideline, rather than hard-fast rules.

You can definitely meet these kinds of entities on the astral, and I can confirm that I have in the past.

I believe that what's meant by Spiritual Realm by CH is the various realms of the dead, as they primarily work with spirits, rather than living entities. It would follow that these entities, when alive, since they aren't from our Earthen Realm, are from the Astral.

Different realms of the Dead are certainly accessible through various methods of Astral Travel, though I would recommend doing some research on the realms of the Dead of whatever culture you're interested in visiting to see if the living are permitted to visit and what you might encounter there. Hell realms, for example, are widely known and easily accessible to the living, but others may not be.

There are also realms inhabited by the Dead who have yet to cross over to their culture's afterlife, most of which are accessible to the living as well, and I believe this is where most of the entities CH works with originate from.

Not all, I think. Some races are too secretive and some realms are restricted that one would require specific rituals etc in order to meet those races and access those realms.

Thanks for all of your informations
