>>1687326Second point I want to make is that the "hallucinogenic" experience is not delirious. The "distortions" experience for example in the visual field can be mathematical mapped to physical sources. When you see things "breathing" they are breathing in rhythm with a defined pattern that is actually real in existing reality. It only alters perception of what is already there it does not spontaneously manifest false images.
With these two things in mind what is different about the experience that you simply cannot have without taking the drug is that your perception of reality is entirely dependent on your childhood, local environment, genetics, family history, language you speak, past history, traumatic experiences and so on and so on. Psychedelics break down your ego and allow you to forget these things for a moment to experience reality in the moment in a pure stream of data with no outside presuppositions imposed on them. Unfortunately this is not something that can be obtained with meditation alone. You have to have the experience first in order to know what you don't know.
