A person’s “bioenergy” field – is essentially their aura or their energy that they are giving off. 

Clients may have seen their practitioners using a pendulum to detect/read their aura before, throughout and after a session to ensure that they have successfully algined their client’s chakras for that session.

Understandably, since we humans cannot see this so-called “bioenergy” field – many will question if it truly exists.  Here is a brief article/study that was completed by the University of Maryland which proof it does.
