Modulating serotonin uptake is what all the anti depressants and anti psychotic drugs do to people, it is the key to consciousness, but more because of the DMT backbone.

Mushrooms are the earths communication mechanism. If you observe mycelium growth it looks a lot like neurons. We consume their information receptors, and intake the information via our pineal gland.

Mushrooms found a way to communicate by modifying the dmt molecule to be orally active without suppressing mono amine oxidase. Dmt is crystalline, and happens to be the native neurotransmitter for interfacing with our brains physiology.

Pretty neat.
