Metaphorical Insight:
Open is the gesture of welcome, the removal of barriers, the unfolding of space. It is both a state of being and an act of invitation. To open is to create possibility, to expose truth, and to invite movement—of people, ideas, breath, or light. In every context, open means the beginning of access, the absence of concealment, and the freedom to enter or connect.
