Even if it was possible, it is unlikely. Not even the priesthood has spoken of such things happening to them.
I believe the O.P. is referring to the section of JoS mainsite that deals with how magick works.
Magick works on plausibility it must be physically possible to exist. I guess that is why technology co-exists with spirituality. For example you can't make a caveman have a gun as that is a highly advanced scientific tool. But it is within the realms of plausibility and existence for a gun. But if your a person who believes you can kill a deer by a machine teleporting unto the field and teleporting the deer's head off and getting the body to fall on the ground to pick it up to take it back to the cave to eat it. THAT is an impossibility, you still need to hunt it and kill it.
Magick and materialization work on a factor of as above, so below. But just because something is astral doesn't make the mental nor physical worthless or useless. Your thinking of only spiritual is ignorant of below and above. While everything is spiritual as H.P.Cobra said a few years ago. In a self-talk in one of his replies or sermon. He went H.P. Cobra aren't you being too spiritual he goes we aren't being spiritual enough.
While spirituality is extremely important the occult is a God thing and turning a civilization's occult off is a sure fire way to doom and gloom them if willed be.
But just because we develop stuff as above or place stuff in the above doesn't make below useless.
For example physically a volcano can explode out from built up pressure. Is that spiritual, absolutely not. But spirituality can describe things of the Volcano to which an entity might for example place a drill-bomb into the bottom of the volcano and explode a chamber so the lava collapses into the chamber and fills it reliving pressure and making the Volcano go dormant for a period of time. For example a machine can make Earthquakes and we can use it to shake at 1 or 2 Richter scale and make a massive fault line relive pressure and make the impending doom go away after spending a few hours doing mini-to-small quakes to erase the pressure on the main faultline.
Also mentality just because a vase in your example exists doesn't mean that someone has a different concept on the vase. You might generate it astrally and download vase technology to a civilization but someone can take the idea and make it vastly better.
Again your simply stating not astral objects i.e. if we astral project and use a astral sword, is it real? Well sure it can be real in that dimension. Humanity is too behind to use astral objects. But I think what your trying to state is can we live astral only. Can a being of higher power be naked underneath in the elements and wear astral clothing to look like they have clothing physically on the 3rd dimension. Is the palace of Satan a physical construct or simply product of his imagination and thoughts. The answer is it's as real as yourself and your computer your reading this. It was designed, engineered, and built by his civilization.
The answer is no not at all the 3rd dimension has it's own rules and regulations even if you merge the Physical with the Spiritual through Spiritual practices you still need to eat, drink, and wear clothing. Non-the less it's an interesting discourse as in advanced societies they live at a higher realm and may in fact use some form of astral objects but probably in another way.
Everything isn't simply astral but it can be astral properties to download the understanding and technology to the plain of existence in our minds to construct the idea. Again the idea sometimes aren't even spiritual. You can make the argument everything happens in the soul first then goes mental then physical but even our own physicality affects us as well as our minds. It's a compounding of the three main realms our personal microverse and the external macroverse.
Some things are spiritual and download and others are uploading to the technology of a civilization from their technology tree. Someone has their own VISION of things their own MIND and sometimes it's simply physical and physical only. Despite the fact you make a point everything is spiritual.
The big cosmic property is the Universe is deeply spiritual at it's core but do note your ignoring ingenuity of other realms of reality. Just because we are encapsulated in a Spiritual Universe does not deny the aspects of mental and spiritual.
