Tat Tvam Asi

Do not ask whether the principle is in this or in that; it is in all beings. It is on this account that we apply to it the epithets of supreme, universal, total...

It has ordained that all things should be limited,

but itself unlimited, infinite.

As to what pertains to manifestation,

the Principle causes the succession of its phases,

but is not this succession.

It is the author of causes and effects,

but is not the causes and effects.

It is the author of condensations and dissipation's (birth and death, changes of state),

but is not itself condensations and dissipation's.

All proceeds from it and is under its influence.

It is in all things but is not identical with beings,

for it is neither differentiated nor limited.

Chuang Tzu

As an unintelligent man seeks for the abode of music in the body of the lute, so does he look for a soul within the Skandhas (the material and psychic aggregates, of which the mind body is composed)

Siddhartha Gautama "The Buddha"

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

The more god is in all things, the more He is outside them. The more He is within, the more without.

Meister Eckhart

...when he can see all things, not in the process of becoming, but in being, and see themselves in the other. Each being contains in itself the whole intelligible world. Therefore All is everywhere. Each is there All, and All is each. Man as he now is has ceased to be All. But when he ceases to be an individual, he raises himself again and penetrates the whole world."

Plotinus

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 unlike itself.

St Bernard

I went from God to God, until they cried from me in me, 'O Thou I!'

Bayazid of Bistun

To gauge the Soul we must gaufe 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

Behold but the one in all things, it is the second that leads you astray.

Kabir

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 in one knowledge.

Eckhart
