My life, my job, my parents, my spouse, my personality, my thoughts, my body. Are these "things" really yours? You might believe that they are since they are close to you, noticed by you. However, they are all temporary, some just passing you by and some are perishable.
If you observe this moment, and this moment only, you will find out that you are already physically safe. Each moment that you are able to take a breath is a moment you are safe to exist in. However, not at every moment, we feel emotionally safe. Our emotional safety is compromised by what we think about ourselves and what others think about us.
