The tools
I was missing

Every tool on this site was born the same way: I needed it and it did not exist. Or it only half existed: paid, slow, or needing three open tabs to answer a single question.

For a while I complained. Then I stopped complaining and started building them.

Today there are five. They are free, they ask for no sign-up, and the calculation happens in your browser: your data never leaves your device.

Instead of complaining about what was missing, I made it.

There is no order

People have asked me which one to start with. The honest answer is that it does not matter.

This is not a course with numbered lessons. It is a workbench. Each tool answers a different question, and the one to open is the one that matches the question you have today.

You do not start with the first tool. You start with your question.

How is this chart built?The Chart

It is the one I use most, for my own study and before every session.

You enter date, time and place, and in a moment you have the complete chart: Personality and Design, gates and lines, and also the colour, tone and base of every activation. Then channels, centres, Type, Authority, Profile, Incarnation Cross and houses.

Two things mattered to me. The first was detail: the chart should not stay on the surface. The second was speed. Right now I do not know of any online tool that does this as fast.

And there is one button I am especially fond of: “Add the transit of right now”. One click, and the sky of this moment is laid over the chart, in blue, together with the channels the transit forms with it. I had not seen that in any other calculator.

What used to take two tools and some mental arithmetic is now a button.

What is moving now?The Transit

I already gave the Transit a whole article. Since then it has grown, and what I use most is the latest addition: the list of the month’s moons and eclipses. You get the four phases, with the gate and line of the Moon and the Sun at each one, and the eclipses with their times. A button takes you to the wheel at that exact instant.

For anyone studying cycles, it is the calendar that was missing.

How does it all connect?The Atlas

It is the familiar bodygraph, but in three dimensions: the nine centres, the 64 gates and the 36 channels.

You turn it, hover over a centre and see its gates; tap a gate and see which channel it belongs to. Every element has its own card, with what it means, an everyday example and a question to observe it in yourself.

I made it comfortable and quick on purpose. A student does not need another book: they need to look up a gate without losing the thread of what they were reading.

For now the Atlas is only in Spanish.

Where do the two moments come from?Before Birth

Every chart is fixed at two moments: birth and, about three months earlier, the instant when the Sun stood 88° of arc behind. We explain it in words again and again, but I had never seen it drawn.

So I drew it. It is a four-and-a-half-minute animation that follows Ra Uru Hu’s teaching: the Program, the Design and Personality Crystals, the Magnetic Monopole and the building of the body. It uses a real chart, with the planets calculated for every moment of the pregnancy.

Some things are understood in a sentence. Others are only understood when you watch them happen.

How does the response feel?Sacral Response

It is the only one that is not a map. It is a practice.

Eighteen questions on three levels for a Generator or Manifesting Generator to train their response: the sound, the movement and what happens in the belly. You do it with another person asking the questions. If you are on your own, you can use practice mode, with the questions shuffled and answering out loud.

It is a reference for anyone who is a Generator and studies the system, and for anyone who accompanies one. The theory of sacral response can be learned in an afternoon. Learning to hear it takes longer.

For now it is available in Spanish and Italian.
