The tale of a Selkie is a similar lore. Shape shifters of the English Isles, Selkie's can slip in and out of their skin. Within their true skin, they are seals of the water world... when out, they become humans of the material world. If someone takes away their skin without their permission, such as a lover, they may still survive, but they become part of a world other than than of their true home. As long as they are within the material world, they will always feel a longing for more connection... for more truth. When they come to reclaim their skin from those who have taken it away, they come fully home.
Without knowing it consciously, we slip out of ourselves and wonder where we have gone. The more we embody ourselves, reclaiming and resting within our own skin... the more we may land in our true home: the vehicle of awakening that is our body.
