“To lose yourself: a voluptuous surrender, lost in your arms, lost to the world, utterly immersed in what is present so that its surroundings fade away. In Benjamin’s terms, to be lost is to be fully present, and to be fully present is to be capable of being in uncertainty and mystery.”
― Rebecca Solnit, A Field Guide to Getting Lost
