From Martin Laird, Into The Silent Land:
Union with God is not something we acquire by a technique but the grounding truth of our lives that engenders the very search for God. Because God is the ground of our being, the relationship between creature and Creator is such that, by sheer grace, separation is not possible. God does not know how to be absent. The fact that most of us experience through most of our lives a sense of absence or distance from God is the great illusion that we are caught up in; it is the human condition. The sense of separation from God is real, but the meeting of stillness reveals that this perceived separation does not have the last word. This illusion of separation is generated by the mind and is sustained by the riveting of our attention to the interior soap opera, the constant chatter of the cocktail party going on in our heads. For most of us this is what normal is, and we are good at coming up with ways of coping with this perceived separation (our consumer-driven entertainment culture takes care of much of it). But some of us are not so good at coping, and so we drink ourselves into oblivion….
The grace of salvation, the grace of Christian wholeness that flowers in silence, dispels this illusion of separation. For when the mind is brought to stillness, and all our strategies of acquisition have dropped, a deeper truth presents itself: we are and have always been one with God and we are all one in God.…
Some who are tediously metaphysical might worry that all this talk of union with God blurs the distinction between Creator and creation. Far from blurring this distinction it sets it in sharper focus. John’s Gospel says we are the branches and Christ is the vine. The branches are not separate from the vine but one with it. If the branch is cut off, you won’t have a branch, for it soon shrivels away. A branch is a branch insofar as it is one with the vine. From the branch’s perspective it is all vine. Speaking of this transformation of consciousness that marks the moving into awareness of our grounding union with God, Meister Eckhart says, “All things become pure God to you, for in all things you see nothing but God.”
