We might say “I’m making a transition” when going from one site or place to another, perhaps at work or to a new home. If we say “I’m transforming” we are in the business of taking who we are and becoming someone different.
One of the oldest images of transformation is the life-cycle of plants. The seed goes into the ground, and something entirely different in form grows, fruits, and creates new seeds. Another central image is the metamorphosis of a caterpillar into a butterfly. Inside the cocoon the caterpillar dissolves completely, and from that jelly another form takes shape. The process of dissolution is uncomfortable at best, and terrifying at worst. One has to risk everything while trusting in an unknown, unproved future.
