Cremation of Care is a ceremony where the participants burn away their worldly cares. In Episode Two: Cremation Of Care we find the Senator taking part in such a ceremony.
Later in Episode Three, after some research, Zach mentions Bohemian Grove. Every year at the Bohemian Grove club a mock child sacrifice is made to a 40ft stone owl. The ritual involves club members, often high ranking businessmen and politicians, cremating their cares in order to clear their conscience for the year ahead.
For more information on Bohemian Grove here is the Alex Jones Film Inside Bohemian Grove.
