A free mind never holds
Identification with anything is a limitation. There is security in thinking that one is the body, the mind, a job, an identity, and so on. Yet implied in this security is the nagging insecurity, because anything within perception is transient, and the ultimate erasure of a separate existence is always pending. The job will end. The body will die. The mind will stop to exist. This is the root of the fear of death.
Identification limits consciousness to a particular part of itself. Consciousness then mistakes it to be only a part, but not the whole field. The field actually never changes, only the content of the field is transient. In such identification, the mind is never free, but bound by the illusory need to survive. In actuality, nothing survives, and such is the very freedom the mind is afraid of. Freedom is this very transience, is this constant change that goes on with abandonment and never looks back.
