Though God be everywhere present, yet He is only present to thee in the deepest and most central part of thy soul.
Thy natural senses cannot possess God or unite thee to Him; nay, thy inward faculties of understanding, will, and memory can only reach after God, but cannot be the place of His habitation in thee.
But there is a root or depth in thee from whence all these faculties come forth, as lines from a centre or as branches from the body of a tree.
This depth is called the Centre, the Fund or Bottom of the soul.
This depth is the unity, the eternity, I had almost said the infinity of thy soul; for it is so infinite that nothing can satisfy it or give it any rest but the infinity of God.
The Deepest Part of Thy Soul
William Law
