Yes. As far as I understand, the only thing Leo really says in the video is: It is possible to achieve exotic states of consciousness. Everything else that Leo says in the video, as far as I can tell, is just attempts to describe how those exotic states of consciousness are like.
If Leo says that in certain states of mind you can get the feeling that you are identical with God, who in turn is identical with everything and with nothing, then sure. I buy that. I'm sure it's possible to reach such states of mind, and I'm sure that such experiences can be very worthwhile.
But near the end of the video (as far as I understand), Leo stresses the distinction between true insights and delusions. I don't understand this distinction. What is the difference between having a true insight that I am identical with God and having a delusion that I am identical with God? If they are both purely states of mind, what is the difference?
Put in another way: Let's imagine two fictional universes. In universe 1, it is possible to achieve the states of mind that Leo describes, and the "insights" you get are true. In universe 2, it is also possible to achieve the states of mind that Leo describes, but the "insights" are delusions.
What is the difference between universe 1 and 2? What could a person in universe 1 do or experience which a person in universe 2 could not do or experience and vice versa?
