[Diederich]

I agree with soylentcola: this is one of the better general purpose descriptions of the general effects and possible advantages of psychedelics.

I can share a pretty concrete benefit that I received in one of my very rare experiences: for the first time, I was able to clearly see some of the not so good edges of my ego. This awareness allowed me to make some substantive modifications in my life that have brought some big, long-term improvements.

Each of my once per year experiences have proved to be beneficial, though often in very subtle and indirect ways. As you said, it's easy to get that mixed up with confirmation bias.
