Shamanism is really working with invisible of psychical energies. Sometimes the existence of these energies can be deduced, rather than experienced directly, at least if one is not fully a shaman or is on the beginning path. One makes sense, for instance, of projection, when one notices certain kinds of behavior that are excessive or overcharged in relation to the practical circumstances surrounding them. But sometimes, and with enough practice, one can start to sense these energies arising, even before they arise, due to some shift in the temperature of the environment. That second way of experiencing these energies is truly shamanic and means one has become very well attuned to one’s environment.
