Layer 6 — The Vedic stack
Follow the Moon through one sign and it crosses several kinds of boundary. A sign gives one address, a nakshatra another, and a pada a finer one still. Jyotish uses these overlapping divisions for different purposes, then adds systems that assign periods, assess strength and describe the calendar.
The sign and nakshatra grids overlap; neither is simply a subdivision of the other. Padas divide nakshatras. Dashas assign time periods, so they should not be pictured as another set of spatial slices.
Nakshatra
A nakshatra is a lunar mansion: a named section of the Moon’s path, imagined
as a place it stays as it travels. In the common 27-sector system, each
mansion spans 360° / 27 = 13°20′. Each also has traditional rulers, symbols
and deities associated with it.
Ashwini begins at 0° sidereal Aries and ends at 13°20′; Bharani follows. This already shows how the grids overlap: two complete mansions and part of a third fit into a 30° sign.
The Sanskrit word is used for stars or asterisms. The equal sectors used in calculation should be distinguished from those historical star groupings. There are also 28-mansion traditions; this guide uses the 27-sector framework.
Pada
Each nakshatra splits into four padas, a word meaning foot or quarter. Dividing 13°20′ by four gives 3°20′ per pada. A Moon at 5° sidereal Aries is therefore in Ashwini’s second pada: it has passed 3°20′ but not yet 6°40′.
Across the zodiac there are 108 padas. There are also 108 ninth-parts of signs: 12 × 9. Their matching widths connect the pada grid to the navamsa, or D9, mapping. The same longitude can be read through both descriptions.
Varga (divisional chart)
A varga remaps parts of the birth chart into another chart according to a chosen rule. The word means division or group; amsha means part. Navamsa means ninth part, so a 30° sign divided into nine portions gives 3°20′ portions—the width we just met in a pada.
D1 is the base rashi chart. D9 is traditionally consulted for marriage and dharma, a term encompassing duty, purpose or right conduct. Other divisions are associated with other subjects:
| Varga | Division | Traditional use |
|---|---|---|
| D1 Rasi | 1 | body, overall life |
| D2 Hora | 2 | wealth |
| D3 Drekkana | 3 | siblings, courage |
| D4 Chaturthamsa | 4 | home, property |
| D7 Saptamsa | 7 | children |
| D9 Navamsa | 9 | marriage, dharma |
| D10 Dasamsa | 10 | career |
| D12 Dwadasamsa | 12 | parents |
| D16 Shodasamsa | 16 | vehicles, comforts |
| D20 Vimsamsa | 20 | spiritual practice |
| D24 Chaturvimsamsa | 24 | education |
| D27 Bhamsa | 27 | strengths, weaknesses |
| D30 Trimsamsa | 30 | misfortune |
| D40 Khavedamsa | 40 | maternal legacy |
| D45 Akshavedamsa | 45 | paternal legacy |
| D60 Shashtiamsa | 60 | past-life karma |
Shodashvarga names the standard set of sixteen divisions listed here. Some traditions and engines also work with higher divisions such as D144. A divisional chart rearranges the original positions under a rule; it does not describe a second physical sky at birth.
The mapping rule matters as much as the division number. Different vargas use different mappings, and the traditional D30 construction uses unequal portions. Multiplying every longitude by the division number is not a universal recipe.
Dasha
The same birth position can also set a clock in motion. A dasha assigns a period of life to a symbolic ruler. Sanskrit dasha carries the sense of a period or condition. Some systems use planetary rulers, while others use signs.
Vimshottari names a 120-year cycle. Its rulers run Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn and Mercury, with periods of 7, 20, 6, 10, 7, 18, 16, 19 and 17 years. The Moon’s birth nakshatra selects the starting ruler. How far it has travelled through that mansion determines how much of the first period has already elapsed.
For example, a Moon halfway through a Venus-ruled mansion leaves roughly 10 years of Venus’s 20-year period. The first period at birth is therefore usually a remaining balance rather than a fresh full-length period.
Inside a mahadasha, or major period, are antardashas, then pratyantar, sookshma and prana subdivisions. Picture smaller intervals inside a larger one: they divide its duration rather than extending it.
| Dasha | Total cycle | Notes |
|---|---|---|
| Vimshottari | 120 years | default; starts from Moon’s nakshatra |
| Ashtottari | 108 years | regional variant |
| Yogini | 36 years | 8 yogini periods |
| Kalachakra | — | nakshatra-group based |
| Chara | — | Jaimini, sign-based, variable lengths |
A period expressed in “years” still needs a year-length convention before it becomes a precise timeline. Sequence, starting rule and time units all matter when comparing dates from different tools.
Ashtakavarga
Ashtakavarga means an eightfold grouping. The seven classical planets and Ascendant act as reference contributors to a rule-based scoring system. A bindu is a point awarded under those rules.
A planet’s individual table is commonly called Bhinnashtakavarga. Sarvashtakavarga combines the seven planetary tables. In a common unreduced scheme the total is 337 bindus, distributed among the twelve signs.
The interesting part is the distribution. Two signs can receive different scores even though the chart’s overall total is fixed. Readers traditionally use that distribution when judging how supportive a transit may be.
A bindu is a rule-based score, not a probability of an event. Reduced and unreduced tables also differ: Trikona shodhana is a reduction procedure, not another name for scoring the sixteen divisional charts.
Shadbala
Instead of scoring sign support, Shadbala brings together six categories of planetary strength. Shad means six and bala strength. The categories look at different parts of a placement and its circumstances:
| Bala | Meaning |
|---|---|
| Sthana | positional strength (sign, house, dignity) |
| Dig | directional strength (which horizon) |
| Kala | temporal strength (day/night, season, year) |
| Cheshta | motional strength (retrograde/speed) |
| Naisargika | natural strength (planet order) |
| Drik | aspectual strength |
Strength is expressed in rupas, with 60 virupas to one rupa. These are traditional scoring units. Directional strength, for instance, concerns a planet’s relation to preferred chart directions; motional strength uses motion rules. The formula and normalisation convention are needed to interpret a total.
Bhavabala means house strength. It has its own house-strength rules rather than simply reusing the six planetary categories unchanged.
Yoga (Vedic)
Yoga means joining or combination. In this setting it names a pattern of placements interpreted together. Pancha Mahapurusha refers to five great-person combinations; Raja to rulership, Dhana to wealth, and Nabhasa to sky configurations.
A name is only the beginning of the rule. Whether a chart qualifies can depend on dignity, houses, exceptions and cancellation conditions. Identifying a pattern and interpreting its promised effects are separate steps.
“Yoga” also names a quantity in the daily panchang. The shared word suggests combination, but a planetary yoga and a panchang yoga are different calculations.
Panchang
A calendar can describe more than the date on a page. Panchang, from pancha (five) and anga (limb), brings together five descriptions of the day:
| Limb | Definition | Length |
|---|---|---|
| Tithi | lunar day (Moon − Sun) | 12° |
| Nakshatra | Moon’s mansion | 13°20′ |
| Yoga | Sun + Moon | 13°20′ |
| Karana | half-tithi | 6° |
| Vara | weekday | 1 day |
A tithi follows the Moon’s angular lead over the Sun, called elongation. Every additional 12° starts another tithi. At an elongation of 25°, the third tithi is active. It is a lunar day measured by motion, so it need not last 24 clock hours. Shukla names the waxing half-cycle and Krishna the waning half.
A karana spans half a tithi, or 6°. Its names follow a prescribed sequence rather than supplying sixty unique labels. Nakshatra follows the Moon’s sidereal longitude. Panchang yoga divides the wrapped sum of Sun and Moon longitudes into 27 portions of 13°20′. Vara is the weekday, conventionally reckoned from local sunrise in this context.
The panchang can change during a civil day. A tithi shown at sunrise may end before midnight. A useful daily account therefore includes boundary times, rather than implying that every limb is constant for 24 hours.
There is a small piece of arithmetic behind the zodiac settings too. A common longitude offset cancels from a difference, such as Moon minus Sun, but not from a sum. That is why the zodiac convention affects panchang yoga differently from tithi and karana. Sunrise, sunset and location complete the local-day context.
Muhurta
Suppose an event can begin at several possible times. Muhurta practice compares those windows using Jyotish criteria, including panchang conditions, transits and other selected rules. The chosen time is traditionally considered auspicious for the intended activity.
The word also names a traditional unit: one thirtieth of a day, conventionally 48 minutes. An electional window called a muhurta need not last exactly 48 minutes.
Rahukalam and Gulikakalam are intervals traditionally avoided for certain activities, commonly allocated from eighths of daylight according to the weekday. Their clock times depend on local sunrise and sunset. Surya Siddhanta names a historical astronomical text and computational tradition, rather than one universal rule for choosing an event time.
KP system (Krishnamurti Paddhati)
Krishnamurti Paddhati means Krishnamurti’s method, after K. S. Krishnamurti. It brings together a sidereal zodiac, Placidus houses and a sub-lord scheme. Each nakshatra is divided into nine unequal portions using Vimshottari proportions, with a ruler assigned to each portion.
The familiar 249-entry KP horary table can seem puzzling: 27 × 9 gives only 243 portions. The extra entries come from splitting portions that cross sign boundaries. There are still nine possible rulers, used repeatedly across intervals.
Lalkitab
Lal Kitab means Red Book. It names a twentieth-century text tradition with distinctive house-based interpretation and remedies. A remedy is a symbolic or ritual action prescribed within that tradition.
Recognising the label tells us that ordinary Jyotish placements are only part of the context. Lal Kitab’s house readings and remedy rules belong to its own textual framework; an ephemeris calculation does not supply them by itself.
Ashtakoot / Dashkoot
In traditional matching, two birth charts supply categories that can be compared and scored. Ashta means eight, dasha ten, and koota a factor or group. The common Ashtakoota scheme awards up to 36 gunas, or points, across eight factors associated principally with the two birth Moons:
| Factor | What is compared in the traditional scheme | Maximum points |
|---|---|---|
| Varna | Spiritual or social category | 1 |
| Vashya | Influence or attraction category | 2 |
| Tara | Birth-star counting relationship | 3 |
| Yoni | Animal-symbol pairing | 4 |
| Graha Maitri | Relationship between Moon-sign rulers | 5 |
| Gana | Temperament category | 6 |
| Bhakoot | Relative Moon-sign positions | 7 |
| Nadi | A threefold constitutional category | 8 |
A dosha is a traditionally adverse condition; a cancellation is a rule that modifies its judgement. Those conditions help explain why a total score alone may not capture a particular tradition’s assessment.
36 points is a scoring maximum, not a percentage scale for marital success. Dashakoota systems use ten factors, but their factors, exceptions and scoring vary by regional tradition; they are not uniformly the same eight plus two.
