Think of how church bells played a role in everyday life in the past. Traveling to Europe, it is still possible to hear the bells ring with stunning regularity. The bells provide a grounding as to the time and place of one’s being. Harmonic attunement is today available through the use of crystal and/or singing bowls. Ayahuascaderos transmit their healing through the use of the ‘Mother’ plant of the Amazon and either whistling or singing their healing through the sound vibrations emanating from their voices.
