propose that an individual can establish resonance with a surrounding natural environment. with a high enough energy level and close enough resonance pattern match, an individual may be able to exit their current environment and possibly re-enter it at some other point.
the distinction between harmony and resonance is important for understanding here. harmony being a more broad and lower energy level shared with an enviroment. i.e. living in harmony with the environment. resonance being a near identical and very specific energy level and pattern matching.
this being based on native americans awareness of their closeness to the natural environment and how to establish various types of resonance with various types of environment. this awaress defining specific types of "quality of mind" i.e. differing forms of spirit.
a hiker, urban walker or a child in amazement of their surroundings could unknowingly establish a resonance and vanish from their location… ability to manage or maintain resonance would likely determine an individuals ability to return.
resonance being defined by synaptic firing patterns in the brain matching in part or whole those existing in the surrounding natural environment.
chants, rituals, prayers, mantras, dancing, fasting, etc assist in these pattern definitions and energy levels devoted to them.
