Very deep observation ! Thanks.
I felt the same, once we lived through a ASC musical experience driven by THC you felt it always stored in our body memory ready to reveal to us again, even without THC, how the music content (visual in my case and derived from the music ) spoke to our consciousness as from a higher level of meaning.
I'm at point where my system can provide a SUSTAINING ASC experience, while the memories or lessons learned from using various mind altering substances can last a lifetime, they can't provide a 'natural' or sustaining ASC experience, they are 'manufactured' experiences in the sense they physically alter our brain chemistry. While it is true all ASC experiences result in brain chemistry changes, better for emotions/feelings to change it vs various physical substances.
