We all come into this world wanting to feel safe. We cling to our mothers as babies, and, as toddlers, tug at our father's trousers to steady ourselves. As we continue to grow we begin to realize that people can hurt us with words and deeds, others can think, behave, and believe differently than us, and we have little control over things like the weather and wars. So we invent little things to make our minds think that yes, we are safe.
Routines become a way of creating a sense of safety.
Surrounding ourselves with a network of friends and relatives also provides us with a feeling of safety. For some, isolation makes them feel safe. Our loved ones can pass on, earth changes can happen without a moment's notice, a fanatic can decide it's their turn to become famous. For me, a sense of safety comes from the fact that I believe there is a God, and that there is a world beyond this one. I feel it is a strength.
