I'm surprised to see a good discussion about psychedelic drugs vis-a-vis spiritual development.
Especially Moth's insights are very valuable and expressed with great clarity, IMO. I take my (imaginary) hat off to that:

@silentone: You raise a good point here about "essentialism" as you call it which is just another mode of distorting reality.
However, better to have a clear position sometimes than just to say "all is relative" about possibly dangerous things.
If psychiatrists can use them in a beneficial way, power to them. However, I am extremely skeptical (to psychiatry in general). I think this is quite dangerous in various ways.
