Everyone has fears. These fears are based in how you identify yourself.
Everyone has identities and wants to maintain those identities. But identities are insecure. They can be fearful or greedy. They can be based on mimetic desire or denial. In other words, the identity can be wanting something others have or not wanting something they do have.
All identity is rooted in something. This causes suffering.
You need to understand what is causing the identities in order to remove the suffering. If you understand what causes the identity, you won't be influenced by the underlying basis of the identity.
