In this paper the Author presents his direct experience with Ayahuasca, an hallucinogenic plant brew employed by Shamans of the tropical rain forests of South America. This drug is commonly thought to be able to bring people into contact with "another" reality from which both practical and spiritual teachings can be obtained. Discovering how this could happen was the main task of the Author during a one month stay in the Peruvian forest. After many disappointing and discouraging results, the Author decided to try Ayahuasca one more time before returning home. During this last sitting, which lasted the entire night, the Author succeded in receiving a great deal of teachings, but in an unexpected and very complex way. On the whole, this experience subjectively looked like a true initiation process which appeared to be (telepathically?) directed by the shaman himself, even if other explanations cannot be discarted.
