"The only way he could heal was to learn how to dream. ... Before he can become a warrior, a man has to leave everything behind and go into the jungle, guided only by his dreams. In that journey he has to discover completely alone, who he really is. Some get lost and never come back. Those who do, will be ready to face all that will come." - The shaman Karamakate in Ciro Guerra's 2015 film 'Embrace of the Serpent'
