Manipura( Solar Plexus Chakra)

As a child I did dance and drama, during one my dance classes, I can remember looking at my dance teacher in confusion when he'd say , project your abdomen to the audience , because it is the centre of your universe . Now i’m an adult and a Complementary Therapist ,I understand the meaning behind his theory, he was referring to the solar plexus (Manipura) " Which is actually the centre of our whole-being"

What does Manipura mean?
