Glossary of Jyotish Terms

A sub-period within a Mahadasha. Each Mahadasha is subdivided into nine Antardashas, one per planet, with durations proportional to the planet's share of the parent dasha.

Antardashas refine timing significantly. A Sun Antardasha within a Jupiter Mahadasha will read differently than the same Sun Antardasha within a Saturn Mahadasha — the interaction between the two planets governs the period's tenor.

The planet that has progressed furthest within its current sign at the moment of birth. Atmakaraka is treated as the karmic signature of the soul's central concern in this lifetime.

In Jaimini-system analysis, Atmakaraka governs the principal axis of the chart. Its placement in the Navamsa, its dignities, and its aspects shape the interpretation of life purpose more decisively than the rising sign in classical Jaimini practice.

The angular difference between the sidereal zodiac (fixed against the stars) and the tropical zodiac (fixed against the equinoxes). Used to convert tropical calculations into sidereal positions.

Vedic astrology is sidereal. The most widely used ayanamsa in modern Jyotish is Lahiri (also called Chitrapaksha). Different ayanamsas yield slightly different rashi and nakshatra positions; rigorous practice fixes one ayanamsa and uses it consistently.

One of twelve houses in a horoscope. Each Bhava governs a specific domain of life — the first house the self, the seventh marriage, the tenth career, and so on through the standard sequence.

Houses are calculated from the Lagna (rising sign). The house a planet sits in usually matters more than the sign for interpretive purposes; classical texts treat Bhava placement as the primary signal of where a planet's influence manifests in lived experience.

The state of a planet when it lies within a small angular distance of the Sun, rendering its effects diminished or compromised in classical interpretation.

The combustion orb differs by planet (Mercury 14°, Venus 10°, Mars 17°, Jupiter 11°, Saturn 15°). A combust planet's significations are read with caution. Classical texts distinguish combustion from cazimi (within ~17') where the planet is conjoined with the Sun's centre and gains rather than loses force.

A timing system that allocates portions of a life to different planets in a fixed sequence. Each planet's period activates that planet's significations during its window.

Vimshottari Dasha is the most widely used system: 120 years total, with Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17, Ketu 7, Venus 20. The starting dasha is determined by the natal Moon's nakshatra. Other systems (Ashtottari, Yogini, Kalachakra) apply in specific chart configurations.

The sign in which a planet's expression is structurally weakest. Each planet has one specific degree in one specific sign where its debilitation is exact.

Sun debilitated in Libra at 10°, Moon in Scorpio at 3°, Mars in Cancer at 28°, Mercury in Pisces at 15°, Jupiter in Capricorn at 5°, Venus in Virgo at 27°, Saturn in Aries at 20°. Debilitation can be cancelled (Neechabhanga) by specific configurations, sometimes producing exceptional outcomes.

A divisional chart obtained by dividing each rashi into three equal segments of 10°. Each segment is ruled by a different sign.

The Drekkana is consulted for matters of siblings, physical body, and immediate environment. It is one of the standard sixteen divisional charts (Shodashvarga) used in deeper chart analysis.

The sign in which a planet's expression is structurally strongest. Each planet has one specific degree in one specific sign where its exaltation is exact.

Sun exalted in Aries at 10°, Moon in Taurus at 3°, Mars in Capricorn at 28°, Mercury in Virgo at 15°, Jupiter in Cancer at 5°, Venus in Pisces at 27°, Saturn in Libra at 20°. An exalted planet produces results in its highest natural register — but the rest of the chart still governs whether those results manifest as outcomes the seeker experiences positively.

The first of the sixteen sacred samskaras in the Vedic tradition — the conscious act of conception with deliberate timing and intention.

Garbhadhana Muhurtha consultations elect auspicious windows for conception by analysing both partners' charts and cross-referencing multiple classical Muhurtha Shastra methods. The aim is to align the conception moment with planetary configurations that support the soul incarnating with the strongest possible foundation.

A celestial body or point that exerts gravitational and karmic influence on the horoscope. The nine grahas of classical Jyotish are Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu.

Rahu and Ketu are not physical planets but the lunar nodes — the points where the Moon's orbit crosses the ecliptic. Despite being mathematical points, they are treated as full grahas with distinct significations: Rahu for unconventional gain and obsessive focus, Ketu for spiritual release and detachment.

A planet that signifies a specific life domain regardless of its house placement. The Sun is karaka for the soul and father; the Moon for the mind and mother; Mars for siblings and energy; Mercury for communication; Jupiter for wisdom and children; Venus for relationships and pleasure; Saturn for longevity and discipline.

Karaka analysis runs parallel to house analysis. To read the marriage axis, the practitioner examines both the seventh house and Venus (karaka for relationships); the two readings are cross-checked. Where they agree, the signal is strong; where they diverge, the question deepens.

The sign rising on the eastern horizon at the moment of birth. Lagna anchors the first house and determines the house positions of every other planet.

Lagna changes every two hours. Even a few minutes of birth-time error can shift the Lagna into a different sign, altering the entire house chart. Where birth time is uncertain, rectification techniques (event-matching, tattva timing, prashna methods) are used to narrow the Lagna before serious analysis.

The major planetary period in the Vimshottari Dasha system. Each Mahadasha lasts between 6 and 20 years depending on the planet and activates that planet's significations as the dominant theme of life during its window.

The opening Mahadasha at birth is determined by which nakshatra the Moon occupies. The sequence then proceeds in a fixed order. Mahadasha analysis is the primary timing tool in Vedic astrology — most major life events can be located within the Mahadasha + Antardasha framework.

The discipline of electing an auspicious moment for a specific action by analysing the planetary configuration at that moment against the proposed act.

Distinct from natal astrology (which reads the chart of a person) and prashna (which answers a question by the moment it was asked), Muhurtha is forward-looking: choosing when to act. Classical Muhurtha Shastra documents over forty parameters (tithi, vara, nakshatra, yoga, karana, lagna, planetary positions, doshas to avoid) that are cross-checked to elect the strongest available window.

One of twenty-seven divisions of the ecliptic, each 13°20' wide, named for a specific star or asterism. The Moon traverses one nakshatra approximately every 24 hours.

Nakshatras are the finer-grained substrate of Vedic astrology beneath the twelve rashis. The natal Moon's nakshatra determines the opening Dasha, governs key timing predictions, and supplies a layer of personality interpretation distinct from the rising sign. Each nakshatra has a presiding deity, a planetary lord, a symbolic shape, and four padas (quarter-divisions) used in deeper analysis.

A divisional chart obtained by dividing each rashi into nine equal segments of 3°20'. The Navamsa is the most important of the divisional charts and is consulted for matters of marriage, dharma, and inner orientation.

A planet's strength is often judged by comparing its rashi placement with its Navamsa placement. A planet weak in the natal chart but strong in the Navamsa (Vargottama if same sign in both) gains durability. The Navamsa is also the primary chart consulted for marriage compatibility analysis in many classical lineages.

The five elements of the Vedic calendar — Tithi, Vara, Nakshatra, Yoga, Karana — that together describe any moment in time. Daily Panchanga is consulted to understand the quality of a day and to elect timing for acts.

Each of the five elements supplies a different layer of information. Tithi tracks the lunar phase; Vara the weekday; Nakshatra the Moon's position; Yoga an angular relationship between Sun and Moon; Karana a finer subdivision of Tithi. Practitioners consult the full Panchanga before any significant act.

The two points where the Moon's orbit crosses the ecliptic. Rahu is the ascending (northern) node, Ketu the descending (southern) node. They are always exactly 180° apart and move retrograde through the zodiac.

Eclipses occur when the Sun and Moon are near a node. In Jyotish, Rahu and Ketu are full grahas with distinct significations: Rahu for unconventional gain, foreign influence, obsessive focus, and the unsatisfied appetite; Ketu for spiritual release, detachment, sudden cuts, and mokṣa-orientation. The nodes complete a full retrograde cycle every 18.6 years.

One of twelve 30°-wide divisions of the ecliptic. Each rashi is ruled by a graha and has a specific quality (cardinal/fixed/dual), element (fire/earth/air/water), and gender.

The twelve rashis are the macro-structure of the horoscope; nakshatras are the micro-structure beneath them. A planet's effects are modulated by the rashi it occupies — its dignity (own sign, exaltation, debilitation, friend/enemy sign) is the first analytical step in classical chart reading.

One of the sixteen Vedic sacraments that mark transitions across a human life — from conception (Garbhadhana) through final rites (Antyeshti). Each is elected at an auspicious muhurtha and performed with specific procedures.

The samskara framework treats human life as a sequence of consciously elected thresholds. Garbhadhana (conception), Jatakarma (birth rites), Namakarana (naming), Annaprashana (first solid food), Vidyarambha (beginning of education), Upanayana (initiation), Vivaha (marriage) are the most widely practised. Each is supported by classical Muhurtha analysis.

A vow or directed intention — a resolve cast at a particular moment, in a particular direction, with the weight of will behind it. The Yoga Sutras describe sankalpa as the seed of action.

In the tantric and Vedic ritual frameworks, sankalpa precedes any significant action: it locates the act in space and time, names the actor and the intended outcome, and binds the act to its purpose. Classical Jyotish treats certain combinations as supportive of strong sankalpa and others as dispersive of it.

The angular separation between Sun and Moon, divided into thirty equal segments. Each Tithi is 12° wide and lasts roughly 24 hours, though the actual clock duration varies with the Moon's speed.

Tithi is the lunar timekeeping unit of the Vedic calendar. Each Tithi has a presiding deity, a quality (Nanda, Bhadra, Jaya, Rikta, Purna), and specific recommendations for acts. Pratipada through Purnima are the bright fortnight; Pratipada through Amavasya the dark fortnight. Auspicious acts are elected on Tithis that classical Muhurtha texts approve.

When a planet occupies the same rashi in both the natal chart and the Navamsa. Vargottama is considered a strength condition — the planet's intent is consistent across the macro and micro views of the chart.

A Vargottama planet is treated as durable. Its effects manifest more reliably than the rashi placement alone would suggest. A debilitated planet that is Vargottama can sometimes produce surprisingly stable results despite its formal weakness.

The principal Dasha system in modern Jyotish, totalling 120 years across nine planetary periods. The starting period is determined by the nakshatra of the natal Moon.

Vimshottari governs the most prediction-rich layer of timing in classical chart reading. Mahadasha + Antardasha + Pratyantardasha analysis can locate events to within a few months in carefully read charts. Most contemporary practitioners treat Vimshottari as the default; alternative systems (Ashtottari, Yogini, Kalachakra) are deployed only where the chart's specific configuration recommends them.
