Empaths suffer from the lack of mastery over their Solar Plexus Chakra. Unmanaged, it absorbs energy from everywhere and is hyper-sensitive to the outside world. Managed, it creates instant stability and inner strength. I'm SO trying to manage better.
Empaths have the ability to scan anothers energy for thoughts, feelings and possibly for past, present, and future life occurrences. Most empaths are unaware of how this really works, and have accepted that they are sensitive to other peoples energy.
