Two schools, one sky

Choose the school, not the page.

Cross the shared Foundation, then walk freely into either school — the Vedic (sidereal) or the Western (tropical), each with its own lessons, Saṅgam checkpoints and capstone. The benches are not yet even between them: the workshop was built on the Indian side first, so several Western rungs drill on a shared instrument, and the West’s own weighing, architecture and lords of the year are worked inside their lessons and gathered in the full reading rather than at a bench of their own. Where both are mastered, the synthesis opens. Your progress is kept on this device.

प्रथमा The Foundation Prathmā · the porch The porch everyone crosses first — what the sky is, how a chart is born, and the two zodiacs that part the schools. Shared by both, gated by neither. Begin the Foundation →

This card is a marker on your shelf, not the paper. The Pramāṇa-patra is the printable record — and it is unsigned, because nobody here invigilated the work.

You have read one sky whole. The Arka Synthesis holds both — sidereal and tropical, meeting in the invariants. The upgrade path is open. Begin the synthesis →

वाक्य
The shape of the whole school

The chart is a sentence.

The masters taught the sky as a language. Every graha and star is a letter; a planet placed in a sign and house becomes a word; dignity and aspect are the grammar that binds them — and when all three meet, the heavens speak a sentence you can read. Our whole curriculum climbs those four rungs, one at a time.

The Curriculum · the full library

The whole path, one ladder.

Every lesson and instrument of the school gathered in one place — the shared Foundation, the two schools, and the synthesis. Each row is marked by the shelf it belongs to; wander freely, or follow a school above for a rhythm.

अभ्यास The Practice Room

Read a chart you have never seen.

Doctrine tells you what a rule is; only a chart in front of you tells you whether you can see it. The room deals a nativity — a real moment, searched until the rule you are drilling is genuinely present in it — asks what it holds, and marks you against the chart itself. Every answer prints its working.

19 rules across two shelves·a fresh nativity each deal·no living person’s chart

Practise until the reading is reflex — then sit the examination.
परीक्षा The Examination Hall

Prove what you can read.

A short examination for every unit of the school — choose-one, choose-all, true & false, fill-the-blank and match-the-pairs — marked the moment you finish, each answer traced back to its lesson.

अभ्यासशाला

The drills studio

Four instruments for the part of the craft that must become reflex — the marks themselves, and the names behind them. They sit here rather than on the Workshop bench, because they are not readings: they are practice, and practice belongs in the school.

यन्त्र
The living instruments

Theory you can touch.

Every lesson hands you a working tool — spin the wheel, drag a graha, scrub the years. Twenty-three instruments, free at the bench; they all meet in the Observatory, where your own chart is read whole.

वेधशाला The Observatory · the workbench

Your own chart, read in six rooms.

Natal · Timing · Compatibility · Together · Event Finder · the Wider Sky — cast once, and every room reads the same saved chart.

The Two Lenses

Every lesson, two ways.

Arka reads each topic through two lenses — the mundane and the spiritual — taught in three movements that meet in mastery. The lineages we learned from →
