What you can do

Ask a question. Read what the masters wrote.

Not keyword search — AI meaning search. It understands what you're asking and finds the passages that answer it, even across different books and authors.

Ask in your own words

“What is the astral body?” · “How is the will trained for magic?” · “What did the Hermeticists mean by mind?” No jargon or citations required.

Meaning-matched passages

Your question is matched against 76.835 indexed passages by meaning, gathering the most relevant lines from across the whole library — not one book at a time.

A cited answer

An AI writes a clear synthesis using only those passages, with numbered citations back to the exact works. Grounded in the texts — never invented.

Answer · from the corpus

The principle of “as above, so below” refers to a universal correspondence between the planes or levels of existence — so that higher truths can be understood through lower phenomena, and the reverse.

1Universal correspondence. The Kybalion [1] holds that there is always a correspondence between the laws and phenomena of the various planes of being; what we observe on one plane lets us reason toward another.

2Creative energy. The same work [2] adds that the principle manifests creative energy through its masculine and feminine aspects across all planes.

3The alchemical reading. Isis Unveiled [3] frames it in alchemical terms — a universal agent, the astral light, that connects all things and can be transformed.

4Spiritual guidance. The Hidden Power [4] reads it as aligning inner guidance with outer action — an inherent connection between the divine and the individual.

Together: a single key for reasoning between the realms of existence — by observation, by alchemy, or by spiritual insight.

Five reasons this is different.

📜

Cited, never invented

Every answer is written only from real passages in the library, with numbered citations. If the texts don't say it, you won't be told they do.

⚖️

Curated & lawful

Each work is hand-vetted, confirmed public-domain and provenance-tracked to its edition. Curated and hosted entirely in the EU.

AI that reads for meaning

AI semantic search reads for intent, not keywords — surfacing the same idea as Blavatsky, Agrippa and Troward each phrased it, side by side.

Unusually, the synthesised answer costs nothing. Premium unlocks the primary sources themselves — full passages, links, and everything below.

Questions

Good to know

Is everything really public domain?

Yes. Every work passes a rights check before it enters the library — the author (and, for translations, the translator) must have died more than 70 years ago under EU law. Each entry is tracked to a specific edition and source. Nothing enters on a guess.

Will it make things up?

The answer is written only from passages retrieved out of the library, and every claim is numbered back to its source. It's a reader of the texts, not a free-associating chatbot — if the corpus is silent on something, the answer says so rather than inventing.

How does the AI work?

Two ways, both grounded in the library. First, an AI embedding model matches your question to the passages that mean the same thing — that's the semantic search. Then a language model reads only those passages and writes the cited answer. It never draws on anything outside the corpus, which is what keeps it honest.

Can I ask in my own language?

Yes. The semantic search understands almost 100 languages, so you can ask in your own tongue and it still finds the passages that mean the same thing — even when the original texts are in another language. The written answer comes back in the language you asked; the cited source passages stay in their original language.

What's actually in the library right now?

160 foundational works across Hermeticism, Theosophy, mental science and ceremonial magic — Blavatsky, Agrippa, Lévi, Waite, Besant, Atkinson, Troward and others — indexed into 76.835 passages you can search by meaning. The collection grows in curated, rights-checked batches, widening across the world's traditions — East and West, ancient and modern.

Why is the answer free but the sources paid?

Because the rare, valuable thing here is the curated primary corpus itself. Anyone can read a summary; Premium members get the actual passages, the links, and the tools to save and study them. It keeps the reasoning open to everyone while supporting the work of building the library.

Is it an app I install?

Lumineus runs in your browser and installs to your phone or desktop like an app (add to home screen) — no store, no download. One place, always up to date. For searching your own documents there is Tabulia, an app for Windows and Android.
