It's funny how they treated cancer:
Treatment was based on the humour theory of four bodily fluids (black and yellow bile, blood, and phlegm). According to the patient's humour, treatment consisted of diet, blood-letting, and/or laxatives.

Oh, that's interesting. I'm reading now that it's also an effective antidepressant, but I'm not sure if it's actually used for that purpose.
I've seen many miraculous claims about them (quick and easy solutions to complicated problems), but if they were so good, I assume the majority of psychiatrists would adopt them as one of the standard methods of treatment. It's great that it worked for you, but there is a reason why rigorous testing is done in science. I think it might be dangerous for people to do this on their own, since they are not experts in this field. I suspect that there might be a few experts who believe that psychedelics are a good method of treatment, but a small fraction is not enough. Sometimes there are bad scientists in every field and we can't just cherry pick the ones we agree with (I'm not accusing you of that, just saying that people do that). I would like to know the truth, though. This is a popular topic lately and I'm curious if it's just pseudoscience or maybe there is something that I'm missing.
I think it might be easy to get addicted to any drug and I know of at least one long lasting effect of psychedelics, but this one seems to be very rare.
Maybe they did it to summon the aliens. Or maybe for the same reason we build expensive churches. Like this one that we have been building for 142 years and it's still unfinished: https://en.wikipedia.org/wiki/Sagrada_Fam%C3%ADlia
This fragment explains how they could have done it:
The most common theory of how prehistoric people moved megaliths has them creating a track of logs which the large stones were rolled along.[49] Another megalith transport theory involves the use of a type of sleigh running on a track greased with animal fat.[49] Such an experiment with a sleigh carrying a 40-ton slab of stone was successfully conducted near Stonehenge in 1995. A team of more than 100 workers managed to push and pull the slab along the 18-mile (29 km) journey from the Marlborough Downs.[49]
My point was that it's not difficult with modern machines at all. But it can also be done with the methods described above. Especially if you work on it for 1500 years.
From britishmuseum.org:
Scientific dating techniques and painstaking archaeological research undertaken around the monument over the last few decades have brought the timeline of the site into focus. It is not possible to talk about 'one' Stonehenge – the monument was built, altered, and revered for over 1,500 years. That is equivalent to around 100 generations – it is worth pausing to let the sheer length of time sink in!
From Wikipedia:
There is little or no direct evidence revealing the construction techniques used by the Stonehenge builders. Over the years, various authors have suggested that supernatural or anachronistic methods were used, usually asserting that the stones were impossible to move otherwise due to their massive size. However, conventional techniques, using Neolithic technology as basic as shear legs, have been demonstrably effective at moving and placing stones of a similar size.[48] The most common theory of how prehistoric people moved megaliths has them creating a track of logs which the large stones were rolled along.[49] Another megalith transport theory involves the use of a type of sleigh running on a track greased with animal fat.[49] Such an experiment with a sleigh carrying a 40-ton slab of stone was successfully conducted near Stonehenge in 1995. A team of more than 100 workers managed to push and pull the slab along the 18-mile (29 km) journey from the Marlborough Downs.[49]
Each stone weights around 25 tons and I found this helicopter that can carry 33 tons: https://en.wikipedia.org/wiki/Sikorsky_CH-53E_Super_Stallion#Specifications_(CH-53E). So we could easily build this today. Probably wouldn't take long at all.
If you want to do some self exploration and learn about yourself, sure it will most often help in a way or another.
I don't doubt that, but I'm sure there are better, healthier ways of doing that. Like talking to a therapist.
We also build stations in space and people live in them.
If a project is popular people will make changes to it every day. But you can look at the repo and judge for yourself.

You mean scammers like Sadhguru and Deepak Chopra?
He would have to build roads too, but I don't see why he couldn't do that. Actually he could have created all of modern technology from the start, but didn't.
