"Interestingly, "growing up" is largely a matter of learning to hide your spirit behind your face, eyes, and language so that we can evade and manage others to achieve what we want and avoid what we fear. By contrast, the child's face is a constant epiphany because it doesn't yet know how to do this. It cannot manage its face. This is also true of adults in moments of great feeling which is one reason why feeling is both greatly treasured and greatly feared.
Those who have attained considerable spiritual stature are frequently noted for their "childlikeness." What this really means is that they do not use their face and body to hide their spiritual reality. In their body they are genuinely present to those around them. That is a great spiritual attainment org gift."
