I've heard similar things from local shamans, if that's even an appropriate way to label them. One guy makes jokes that he has a TAFE certificate 2 in shamanism. Jokes aside they tend to think that there is a need that is becoming more urgent for people to wake up to our destructive ways and Ayahuasca is helping a lot of people to wake up.

After all my experiences with Ayahuasca and DMT I feel that they are the vessel of a message (spirit?) that's been encoded into all life and the message seems to have its own intelligence as though civilisation follows a predictable path and then comes to a crisis point where the message needs to be headed or all will be lost. The last few times I received the "message" it seemed a lot more urgent than it did 10 years ago.

If there ever was a time when when this world needed Ayahuasca now would be that time.
