Serious research suggests psychedelics may be an effective cure for depression, anxiety, post-traumatic stress, and addiction, among other things. This article also compares reported experiences under psychedelics to meditation, which I found interesting.
What is happening when a person meditates? If you meditate in a dedicated way, for long enough, most people say that they start to experience a spiritual change. Why did meditation make people feel they were being changed in a way that was mystical — and what did that even mean? He stumbled across the psychedelics studies from the 1960s, and it seemed to him that the way people described feeling when they took psychedelics was very similar to the way people described when they were in a state of deep meditation. He began to wonder if they were, in some strange sense, two different ways of approaching the same insight. Could investigating one unlock the secrets of the other? …
When you take a psychedelic, most people will have a spiritual experience – you get a sense that your ego-walls have been lowered, and you are deeply connected to the people around you, to our whole species, to the natural world, to existence. But it turns out the intensity of the spiritual experience varies from person to person. For some people, it will be incredibly intense; for some people, mild; and some people have no spiritual experience at all. At Johns Hopkins, the team discovered that many of the positive effects correlate very closely with the intensity of the spiritual experience. So if you had a super-charged spiritual experience, you got the benefits very heavily; and if you had no spiritual experience, you didn’t have many positive effects.
Okay, I don’t usually go here, but let’s say just for the sake of argument that religion is not objectively true. Then these spiritual experiences people tend to have while under the effects of drugs, meditation, and prayer actually come from inside us, are baked into our minds in some way. And maybe people who have more of them really are happier and better off, which would seem to be a good thing maybe even if they are not objectively true.
