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.
I don't know if we ever feel anxious. That feeling of uncertainty, of not knowing, as if floating in mid air. There is nothing to grasp on, and everything, life, marriage, career, future, and all that is implied in what we call living, seems to exist on tenuous structures, a tower made of paper, and capable of falling apart any minute. I think this is our life everyday. This creeping anxiety, although we suppress it, or distract ourselves from it with music or shows or incense, this anxiety is always waiting to explode. And when it does, it might become depression, uncontrollable anger or loneliness, and all forms of neurotic breakdowns. If we could, from the very root, dissolve this sense uncertainty, then we could perhaps live with a background of absolute security. After all, security is what most of us seek. A sense of being safe, protected, certain. So, it is quite important to ask, what is the cause of our anxiety and uncertainty? How is one to live on a ground utterly immovable, like walking on earth, and therefore anxiety has no root to flower?
