In survival we learn to meet our own needs. Through skill, ingenuity, and perseverance, we have been meeting our needs since time's foggy beginnings. When it is cold, we insulate and stay dry. When we are thirsty we find, purify and drink water. When we are hungry we find and harvest plants and animals.
It is just that simple, and it is not. In learning survival we learn a sharp lesson, modern humans have taken a bigger step away from the land than they may know. Survival requires deep and real connections to the Earth. There is no space for our ego's, our childish wants, or our cultures comfort with waste. Survival skills must take root within our minds. Our attitudes and clarity, our ability to deal with stress and still remain aware of the reality around us is of the utmost importance.
And then the stress all falls away. Your needs are met. You are warm, dry, and full. Sitting by a fire in the darkness of night with dear friends. You realize then that you have lived another day on this Earth without spending money. Without using a phone, a computer, a refrigerator, a single piece of plastic.
There is nothing like this freedom and it changes who you are and how you see the world.
