Never underestimate the power of compassionately recognizing what's going on. - Pema Chödrön
There's an excellent new essay titled Navigating the Collapse of Civilization: a Spiritual Map by Carolyn Baker, Ph.D. It covers the positives that can result from a Peak Oil-induced collapse of civilization as we know it. There are actually quite a few of them. This is a highly recommended read.
Moreover, collapse may bring meaning and purpose to our lives which might otherwise have eluded us. In our linear, progress-based existence, we rarely contemplate words like “purpose.” With civilization's collapse, we may be forced to evaluate daily, perhaps moment to moment, why we are here, if we want to remain here, if life is worth living, if there is something greater than ourselves for which we are willing to remain alive and to which we choose to contribute energy. These decisions probably will not be made in the cozy comfort of our homes, but in the streets, the fields, the deserts, the forests, and beside forgotten rivers and trails. Purpose will rapidly cease being about what we can accomplish and will increasingly become more about who we are. In a collapsing world, the so-called “purpose-driven life” will no longer exist. Humans will be “driven” by only one issue: the determination to survive and assist loved ones in surviving. From that quest for survival will emerge authentic purpose, which will undoubtedly not resemble anything we can imagine today.
