Nations are named, some marked outwardly by their rituals and some not, yet the same thing is said of all of them: uncircumcised in the heart. What is cut away on the outside means nothing while the heart itself stays closed and hard.
This points to the difference between outer form and inner awakening. You can carry every external sign of belief and still live entirely from the defended, separate self that keeps the heart shut. The real opening happens inwardly, as the ego's hard shell falls away and presence begins to flow through you. Until that happens, all people stand in the same place whatever their labels: still asleep. The change that matters is not on the surface of your life but in the awakening of awareness within you.
