A closed 1. chakra means difficulties connecting to other people, a feeling of loneliness, abandonement, a feeling of being let down ... no earth connection, no body connection ...
The door is closed to most feelings, while looking for somewhere else to belong, to be part of something else.
Lack of worth leads to a feeling of: "I'm nobody", which leads to actions of trying to proof your own worth to the world. How many of us haven't done or are trying to do that? And always come up with the feeling of not-good-enough?
