Every chapter before this one is about something outside you. A mushroom, a cactus, a vine, a toad, a fish, a jar of honey. Things you have to go and find.
This chapter asks a different question, and the answer reframes everything before it.
DMT was identified in human blood in 1965. The enzyme that makes it, INMT, is present in human tissue. A 2019 study demonstrated DMT synthesis in rat brain tissue.
You are not visiting this chemistry. You are made partly of it.

The receptors were already thereAnd so was the key
Consider what a receptor actually is. It is a lock. Locks do not evolve so that something from outside can open them — they evolve because something inside is already opening them.
Anandamide is the cleanest example. Identified by Mechoulam's group in 1992, it is the body's own cannabinoid, and it is named from the Sanskrit ānanda — bliss. Somebody in that laboratory was paying attention to more than the chemistry.

StrassmanAnd the part the book will not overstate
Between 1990 and 1995, Rick Strassman administered roughly 400 doses to 60 volunteers at the University of New Mexico — the first human psychedelic research in the United States in two decades.
His pineal-gland hypothesis remains unproven, and this page says so plainly.
The idea that the pineal gland floods the brain with DMT at birth and death is repeated everywhere as though it were established. It is not. It is a hypothesis, it is interesting, and it has not been demonstrated.
Enthusiasm without honesty is just marketing.

What is established is stranger and quieter. Near-death experiences are reported by roughly one in ten cardiac arrest survivors. A 2018 study compared NDE accounts against DMT accounts and found substantial linguistic overlap — people reaching for the same words without knowing they were doing it.
And none of it requires a substanceThis is the real finding
Here is what the chapter is actually for.
- REM sleep. A psychedelic state you enter nightly and mostly fail to notice.
- Drumming at roughly 4–8 Hz, which corresponds to the brain's theta range. Not a coincidence, and not new.
- Holotropic Breathwork, developed by Stanislav Grof specifically after LSD research was closed off. He needed another door and found one.
- Sufi whirling. The San trance dance. Different continents, different centuries, overlapping destinations.
Lilly's tank, and the best argument in the book
In 1954, John Lilly built an isolation tank to remove every sensory input he could and expected the mind to go quiet.
It did the opposite.
Take away the world and the brain supplies one. Not as a malfunction — as a default. Whatever this capacity is, it is not an intrusion, and it is not something the mushroom gave you.
You were designed and built for this. What an exhilarating and most extraordinary thought!
