What Is Unitive Knowledge?

Unitive knowledge is not a doctrine that all religions are the same. It is a question about a kind of knowing that many traditions describe, and about how far their descriptions agree.

    The One and Brahman

    Plotinus and Śaṅkara never read each other, yet both describe a first principle beyond ordinary predication. The resemblance is striking; so is the difference.

What is unitive knowledge?

Unitive knowledge is the study of how humanity has understood ultimate reality, and whether beneath the diversity of traditions there are real convergences, and real disagreements.

The Way of Unitive Knowledge

Seven essays on the knowledge the contemplative traditions put above all others: what it is, why we lack it, and the path they describe toward it, from the first turning to the return to ordinary life.
  1. Knowing by Becoming

    What this knowledge is: not knowing about, but knowing by becoming.

  2. The Forgetting

    Why we do not already know what is said to be so close.

  3. The Turning

    Metanoia itself: longing, disillusion and the first step.

  4. The Purification

    Why every path is moral before it is mystical.

  5. The Practice of Attention

    Contemplation, prayer, meditation and inquiry, and the place of grace.

  6. Darkness and Unknowing

    The passage beyond concepts, its dangers, and the need for discernment.

  7. Union and Return

    What the traditions say is found, and the return to the world.

The Sevenfold Path

Seven essays on the maps of the inner ascent that the traditions draw in seven stages: Teresa’s mansions, ʿAṭṭār’s valleys, the Yoga Vāsiṣṭha’s stages of knowledge, Buddhaghosa’s purifications, the Buddha’s factors of awakening, Augustine’s levels of the soul, and what the maps share.
  1. The Seven Mansions

    Teresa of Ávila’s Interior Castle: the soul as a castle with God at its centre.

  2. The Seven Valleys

    ʿAṭṭār’s Conference of the Birds: thirty birds, and a king who is a mirror.

  3. The Seven Stages of Knowledge

    The Yoga Vāsiṣṭha: from the wish for the good to the state beyond waking and sleep.

  4. The Seven Purifications

    Buddhaghosa’s Path of Purification: seven chariots, each only as far as the next.

  5. The Seven Factors of Awakening

    The Buddha’s seven qualities of a mind ready to wake. Forthcoming.

  6. The Seven Levels of the Soul

    Augustine’s ascent from life itself to contemplation. Forthcoming.

  7. Why Seven?

    The maps compared: one path, or several? Forthcoming.

The Bhagavad Gītā

The Gītā’s way for those who stay in the world, and the Mahābhārata teachings around it, now in the Library’s reader.

Essay

Action Without Attachment

Must the seeker leave the world? The Bhagavad Gītā was spoken to a man who wanted to, on a battlefield, and its answer is the way of action without attachment: to act fully and give up the claim to the fruit. What that teaching asks, how the Mahābhārata tests it, and how it has been misread.
