Behold but One in all things; it is the second that leads you astray.

Kabir

My Me is God, nor do I recognize any other Me except my God Himself.

St. Catherine of Genoa

In those respects in which the soul is unlike God, it is also unlikeitself.

St. Bernard

I went from God to God, until they cried from me in me, ‘ O’ thoul!’

Bayazid of Bistun

To gauge the soul we must gauge it with God, for the Ground of
God and the Ground of the Soul are one and the same.

Eckhart

The spirit possesses God essentially in naked nature, and God the spirit.

Ruysbroeck

The knower and the known are one. Simple people imagine that
they should see God, as if He stood there and they here. This
is not so. God and I, we are one in knowledge.

Eckhart

The Beloved is all in all; the lover merely veils Him;
The Beloved is all that lives, the lover a dead thing.

Jalal-uddin Rumi
