Presencing is our natural ground state. Union with Being itself. There is no mystery about it. As easy as taking a deep breath and letting go when it's time. Every moment is meditation. I call it presencing to emphasize that is it a process, a verb, a doing not-doing. So beautiful so easy and natural.
Sometimes the pain of existence is too much. So we try to forget our bring here. Don't believe it - we cannot go away. We are condemned to consciousness now and forever. Some times raging in pain, we forget that that's also being here, being-meditation. Heaven, Hell, Purgatory and Limbo are all part of the show. No one promised us an eternal bowl of cherries. The Kingdom of God is always with us. But sometimes we must wait and suffer.
Presencing can also be called "meditation practice". We practice meditation in order to train our mind, to sharpen attention to the constantly emerging inner monologue that goes on inside of us; this is mostly meaningless babel - but it's our babel. We many even notice what we are doing. We keep unconsciously reinforcing our own thought patterns. Confirming back to ourselves what we assume is true of ourselves.
What if we lie to ourselves? How can we tell? Perform self observation. Look for the ego. What is ego? Ego is like a cell wall that defines "inside and outside". Become friends with our own limits - a journey toward freedom begins.
