Note 232 — Chapter XVI · CEREMONIALS AND RITUALS
Reading edition
Fasting is par excellence the characteristic method of superinducing religious feeling in order to bring about a state of mind in which the world of sense-impressions was shut out and in which auto-suggestion or hallucinations were predominant (Boas).
For one ceremony at Taos eighteen months of self-isolation is exacted of the priests, when no message from family or home is permitted, whatever the emergency.
