The measured angle between the tropical zodiac (seasons) and the sidereal zodiac (stars) — currently about 24 degrees and slowly growing, because Earth's axis wobbles over a ~25,800-year cycle (the precession of the equinoxes). Every Vedic chart subtracts an ayanamsa from tropical positions; Lahiri is the official Indian convention and our default, with Raman, Krishnamurti, and Fagan–Bradley offered for other lineages.

The sub-period inside a Vimshottari mahadasha. Each major chapter subdivides into nine smaller ones in the same planetary order, each lasting a proportional share. The antardasha describes the sub-plot: a Venus year inside a Saturn decade feels different from a Mars year inside it. Timing in Jyotish is read maha + antar together, like a key signature and the phrase being played inside it.

Sanskrit for 'seizer' — the nine 'planets' of Jyotish: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the two lunar nodes Rahu and Ketu. The name is the theory: a graha is that which grips consciousness and holds it to a storyline.

A major planetary chapter in the Vimshottari system, lasting from 6 years (Sun) to 20 (Venus). Which chapter you begin life inside — and how far along — is seeded entirely by the Moon's nakshatra at birth. People often recognize their mahadasha changes in hindsight as the chapter breaks of their biography.

One of the 27 lunar mansions dividing the sidereal zodiac into 13°20' segments — the Moon's nightly resting places. Each has a presiding deity, a symbol, an animal, a temperament, and a planetary lord; together they are Jyotish's oldest layer, older than the twelve signs. The Moon's nakshatra at your birth (your janma nakshatra) names your emotional habitat and seeds the entire Vimshottari timeline. Our charts give the nakshatra and pada of every planet and of the Ascendant and Midheaven.

The ninth harmonic chart: each sign divides into nine padas of 3°20', which reassemble into a second complete chart. Tradition reads it for marriage and partnership, dharma, and the inner fruit of the natal promise — the D1 is the tree, the D9 the fruit hidden inside it. A planet in the same sign in both charts (vargottama) gains uncommon strength.

A quarter of a nakshatra — 3°20', the smallest commonly-read unit of the sidereal zodiac. The four padas step each mansion through a fire–earth–air–water sequence and map one-to-one onto the navamsa: knowing a planet's pada is knowing its D9 sign. Pada lords add a final grace note to any placement.

The root chart of Jyotish — the sidereal signs exactly as they stood at birth, before any division. All the divisional charts (vargas) are derived from it, which is why it is called D1: the ground floor of the whole Vedic reading.

The zodiac measured against the fixed stars themselves, used by Jyotish and by Western sidereal astrologers. Because of precession it drifts about one degree every 72 years relative to the seasons — hence the ayanamsa correction, and hence your 'Vedic sign' often being one sign earlier than your tropical one. Neither zodiac is wrong; they measure different skies.

The 120-year master clock of Jyotish: nine planetary chapters — Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17 — whose order is fixed and whose starting point is seeded by the Moon's nakshatra at birth. Where you begin in the wheel, and how much of that first chapter remains, is the first timing fact of a Vedic reading.
