I think learning about the existence of DMT in particular has changed my views on a lot of things. In terms of experience people are going to other worlds and universes. That is a subjective fact as Benny Shanon said in "The Antipodes of Mind". And you will therefore be impressed by the DMT experience depending on whether you think subjectivity is an important property in our universe that needs to be explained. In my opinion, science undervalues subjectivity as a phenomenon because it doesn't really understand subjectivity. There are also outdated paradigms that hold research back. Either way, in my encounter with learning about psychedelics (which is still evolving) I feel like I can start to take spirituality seriously for the first time. The overall message from ayahausca appears to be "live in mystery" (which I could mean to be "live in the questions"), and it's nice to know that there is an entity in nature giving us that courage.
