The end of an era is an accurate description of a process that shamans go through in dismantling the structure of the world they know in order to replace it with another way of understanding the world around them. I've endeavored, from the very instant we met, to introduce you to the cognitive world of the shamans of ancient Mexico.

The world of the sorcerers of ancient Mexico is different from ours, not in a shallow way, but different in the way in which the process of cognition is arranged. In our world our cognition requires the interpretation of sensory data. The universe is composed of an infinite number of energy fields that exist in the universe at large as luminous filaments. Those luminous filaments act on man as an organism. The response of the organism is to turn those energy fields into sensory data. Sensory data is then interpreted, and that interpretation becomes our cognitive system.

The end of an era means that the units of a foreign cognition are beginning to take hold. The units of your normal cognition, no matter how pleasant and rewarding they are for you, are beginning to fade. A grave moment in the life of a man!
