Seven years later, Edward and Emily have two daughters, are on the brink of divorce, and reunite with the couple who first introduced them. When Edward hears of the Hinchi tribe whose members experience shared hallucinatory states, he travels to Mexico to participate in their ceremony. During the climb up into the Hinchi hill country (a plateau covered in spectacular mushroom-shaped ventifacts) Edward is told by his guide, Eduardo Echeverria, that the Hinchi use in their ceremonies a potion containing the sacred mushroom "Amanita muscaria" and the shrub "Sinicuiche" ("Heimia salicifolia"), which they are collecting for next year's ceremonies. The tribe calls "Heimia salicifolia" by a Hinchi name meaning "first / primordial flower" in recognition of the deep memory states which it can evoke. An indigenous elder ("the brujo") is seen with a root (presumably intended to be a Heimia root) in his hand, which he asks Edward to hold, before cutting his hand in order to add some drops of his blood to the mixture he is preparing. Immediately after consuming the mixture, Edward experiences bizarre, intense hallucinations, including one of the petrifaction and subsequent erosion by blown sand of Emily and himself. The following morning, Edward leaves the Hinchi plateau under a cloud, having killed, while in his intoxicated state, a large specimen of the Hinchi's sacred monitor lizard (which a petroglyph shown in the dream sequence shows that they believe to have given them the sacred mushroom in the mythic past). He returns to the U.S. with a sample of the Hinchi potion for analysis by his colleagues and further self-experimentation, and continues taking it in order to take his exploration of altered states of consciousness to a new and higher level.
