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 complete on its own, each with its lessons, living instruments and Saṅgam checkpoints. 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 →

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.

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.

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-six 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 →
