A Great Question

What does unity mean?

Identity, union and wholeness are not the same.

Framing

“All is one” is perhaps the most common summary of mystical teaching, and one of the least clear. It can mean that there is only one thing, and that multiplicity is an illusion. It can mean that everything is interconnected, a single web or organism. It can mean that everything comes from one source and returns to it. Or it can mean that the soul and God are united in love, while remaining two.

The traditions use the language of unity in all these senses, sometimes within a single text. Comparing them without distinguishing the senses produces false agreements and false disagreements: two traditions may both say “one” and mean different things, or say different things and mean something close.

Clarity here prevents much confusion. The perspectives below show unity as identity, as union, as oneness of source, and as the oneness of God.

Perspectives

Voices from several traditions, each in its own terms. They are set side by side to be compared, not ranked.

Advaita Vedānta, Śaṅkara
Scholarship
Unity as identity: the self is Brahman, and there was never a second; multiplicity is an appearance due to ignorance.
Sources: The Vedânta-Sûtras, with the Commentary by Sankarâkârya
Neoplatonism, Plotinus
Scholarship
Unity as source: all things are one by depending on the One, and the soul’s goal is union with it, in which seer and seen are no longer two.
Sources: The Enneads
Carmelite mysticism, Teresa of Ávila
Scholarship
Unity as union: in the spiritual marriage the soul and God are one, as rain falling into a river, yet the soul remains a creature, and returns to serve.
Sources: The Interior Castle
Islam, al-Ghazālī
Scholarship
Unity as the oneness of God: the highest tawḥīd is to see nothing in existence but God, though those who see it should not say that they are God.
Sources: Al-Ghazzālī’s Mishkāt al-Anwār
Sufism, Ibn ʿArabī
Scholarship
Unity of being: there is one reality, God, and the world is its self-disclosure, “He and not He”, neither identical with God nor other than God.
Sources: Ibn al’Arabi: The Bezels of Wisdom

Reflect

In what sense are you one with what you love?
