Shamanic Ayahuasca Visions

(The 'icaros' are 'medicine'  chants which spontaneously come to a shaman in dreams, during 'dietas' or passed down from previous lineages of healers. The singing or whistling of  icaros are used during the ayahuasca ceremonies to invoke spirits and allies, to heal, to induce particular visions and modulate their intensity)
