What Is All This?
The universe, existence, reality — the one ground behind all that is
Look at the sheer multiplicity of the world — galaxies and grains of sand, joy and grief, ten thousand things arising and passing. Is this the final reality, or does something single and unchanging lie beneath it? The seers of the Upanishads answered with one of the boldest claims in philosophy: Brahma satyam jagat mithya — Brahman alone is real; the world is appearance. Behind every form, they held, is one infinite, formless reality — Being, Consciousness, Bliss — and "all this is verily Brahman" (Chandogya Upanishad 3.14.1), as waves are nothing but the ocean. Each tradition below reaches for that one ground and names it differently. But they do not all agree on its nature — and those disagreements, set out honestly, are among the deepest questions a human being can ask.
How 12 Traditions Describe Ultimate Reality
"Brahma satyam jagat mithya" — Brahman is real, the world is appearance, the self is none other than Brahman (attributed to Adi Shankara). Brahman is the one infinite reality: not a being among beings but Being itself — Sat-Chit-Ananda. "All this is verily Brahman" (Chandogya Upanishad 3.14.1). The manifold world is its appearance through maya — real as experience, not as the final word.
"He is the First and the Last, the Manifest and the Hidden" (Qur'an 57:3). Tawhid — the absolute oneness of God — is Islam's foundation: there is one necessary Reality, al-Haqq, on which all else depends. "Wherever you turn, there is the Face of God" (Qur'an 2:115). Creation is fully real, yet it subsists moment to moment only by the will of the One.
"In Him we live and move and have our being" (Acts 17:28). God is not one object within the universe but the ground of all existence, in whom everything holds together. The mystic Meister Eckhart pressed further still to the Godhead "beyond God" — the silent, nameless source from which even the personal God and all creation flow.
Here the question turns. Buddhism points not to a ground but to Śūnyatā — emptiness: nothing possesses inherent, independent existence; all things arise in dependence on others (pratītyasamutpāda). "Form is emptiness, emptiness is form" (Heart Sutra). The Dharmakaya, reality's "truth-body," is not a cosmic substance but the very suchness of things seen without illusion.
The Guru Granth Sahib opens with a number and a sound: Ik Onkar — One Reality, the single creative force pervading all. "There is but One; Truth is its Name; the Creative Being" (Mool Mantar). This One is both formless (nirgun) and present within every form (sargun) — the whole cosmos is the play of the One, who created Himself and assumed His Name.
Kabbalah names ultimate reality Ein Sof — "the Infinite," "Without End": God utterly beyond name, image or comprehension. From this hidden, boundless source, creation unfolds through the ten Sefirot, channels of divine light. The world is real, willed and good — yet it is a veil and a vessel for an Infinite that forever exceeds it.
"The Tao that can be spoken is not the eternal Tao" (Tao Te Ching 1). The Tao is the nameless source and pattern of all that is: "The Tao gives birth to One, One to Two, Two to Three, and Three to the ten thousand things" (Tao Te Ching 42). Not a god creating from outside, but the way reality flows of itself — present in everything, grasped by none.
The Bahá'í writings hold God to be an unknowable Essence, infinitely beyond the reach of mind — "exalted beyond every human attribute" (Bahá'u'lláh). That Essence cannot be known directly, only its attributes, mirrored in creation and made known through the Manifestations. Reality is one, emanating from a single Source whose innermost nature stays forever hidden.
Ahura Mazda — the "Wise Lord" — is the one uncreated Creator, the source of all that is good, luminous and ordered. From Mazda flows Asha, the true order woven through the cosmos, ever opposed by Druj, the lie and disorder. Reality is fully real and fully moral: a created world, good in its origin, and a stage on which order is chosen over chaos.
Jainism needs no creator. Reality is eternal and uncreated — six everlasting substances (dravyas): souls (jiva) and the non-living realities of matter, space, time, and the media of motion and rest. The universe was never made and will never end; it runs by its own law. And because reality is infinitely many-sided (anekantavada), no single view can capture the whole of it.
Ibn Arabi gave the boldest Islamic formulation: Wahdat al-Wujud, the "Unity of Being." There is, in the end, only one Reality — al-Haqq — and the cosmos is its self-disclosure (tajalli), God beholding Himself in the mirror of creation. Every existing thing is a ray of the one Light. "Everything perishes save His Face" (Qur'an 28:88).
Confucian thought looks less to a creator than to an order. Tian — Heaven — is the source of the moral and natural way; and the Neo-Confucians named Li, Principle: the rational pattern inherent in all things, from a blade of grass to the human heart. Reality is a single coherent order, and to grasp the Li of things is to find one's right place within the whole.
The One and the Many
Set these traditions side by side and a striking convergence appears: the world's dazzling multiplicity is not, for most of them, the final word. Behind or beneath the ten thousand things they point to one reality — Brahman, the Tao, Allah, Ein Sof, the Godhead, the One Creator. "All this is verily Brahman," say the Upanishads; the wave is never separate from the ocean. To awaken, in this shared intuition, is to stop mistaking the surface for the depth — to glimpse the single ground from which every passing form arises.
But they do not all say the same thing, and it flattens them to pretend otherwise. They divide on whether the world is fully real — a genuine creation, as Islam, Judaism, Christianity, Zoroastrianism and Sikhism affirm — or finally appearance, as Advaita's maya suggests. They divide on whether the One is personal, a God who wills, knows and loves, or impersonal: the nameless Tao, the formless nirguna Brahman. And two traditions unsettle the very question. Buddhism points not to a ground at all but to Śūnyatā — emptiness, no independent substance anywhere, only dependent arising; and Jainism dispenses with a creator entirely, holding the universe eternal, uncreated and irreducibly plural. These are not minor footnotes — they are among the deepest fault lines in human thought. The honest reader holds the convergence and the disagreement together, collapsing neither.
