The 494 Indicators: How Vedtara Scores Behavioral Tendencies

Most astrology platforms present chart data and leave interpretation to the reader. Vedtara takes a different approach: it computes behavioral probability scores — numerical assessments of how likely specific behavioral tendencies are to manifest, given the full context of your chart, current dasha periods, and active transits.

This article explains exactly how that computation works. We believe in radical transparency — if we are producing a number that describes your behavioral tendencies, you should understand where that number comes from, what assumptions it encodes, and where its limitations lie.

What Is an Indicator?

An indicator is a specific planetary condition that, according to classical Vedic astrological texts and systematized practitioner knowledge, correlates with a particular behavioral tendency.

Each indicator has three components:

A condition: A testable planetary fact about your chart. Examples:
- “Mars is placed in the 8th house”
- “The 2nd lord is conjunct Rahu”
- “Saturn aspects the Moon from the 10th house”
- “The 10th lord is in a nakshatra ruled by Ketu”
- “Venus is in Pushkara Navamsha”
A target tendency: The behavioral pattern this condition maps to. Examples:
- “Financial risk tolerance”
- “Conflict avoidance”
- “Entrepreneurial drive”
- “Emotional resilience under pressure”
A weight: How strongly this condition pushes toward or away from the tendency (explained below).

Vedtara’s engine contains 494 such indicators, each manually curated from classical texts (Brihat Parashara Hora Shastra, Phaladeepika, Saravali, Jataka Parijata, Uttara Kalamrita) and systematized practitioner observations. No indicator exists without a traceable source.

The 32 Condition Matchers

Each indicator’s condition is evaluated using one or more of 32 condition matchers — the atomic tests that determine whether a planetary condition is true for a given chart.

The 32 matchers fall into several categories:

Placement Matchers

Planet in house: Is graha X in bhava Y?
Planet in sign: Is graha X in rashi Y?
Planet in nakshatra: Is graha X in nakshatra Y?
Planet in navamsha sign: Is graha X in D9 sign Y?
House lord in house: Is the lord of bhava X placed in bhava Y?

Dignity Matchers

Exaltation: Is the planet in its sign of exaltation?
Debilitation: Is the planet in its sign of debilitation?
Own sign: Is the planet in a sign it rules?
Moolatrikona: Is the planet in its moolatrikona range?
Friend’s sign: Is the planet in a sign ruled by a friend?
Enemy’s sign: Is the planet in a sign ruled by an enemy?

Relationship Matchers

Conjunction: Are grahas X and Y in the same house?
Aspect: Does graha X aspect graha Y (using Vedic aspect rules)?
Mutual aspect: Do grahas X and Y aspect each other?
Nakshatra exchange: Is graha X in a nakshatra ruled by graha Y?
Sign exchange (Parivartana): Are two planets in each other’s signs?

Strength Matchers

Shadbala threshold: Does the planet’s six-fold strength score exceed a threshold?
Ashtakavarga bindus: Does the planet’s benefic-point score in its occupied sign exceed a threshold?
Vargottama: Is the planet in the same sign in D1 and D9?
Combustion: Is the planet within combustion range of the Sun?
Retrograde: Is the planet in retrograde motion?

House-Based Matchers

Kendra placement: Is the planet in a kendra (1st, 4th, 7th, or 10th house)?
Trikona placement: Is the planet in a trikona (1st, 5th, or 9th house)?
Dusthana placement: Is the planet in a dusthana (6th, 8th, or 12th house)?
Upachaya placement: Is the planet in an upachaya (3rd, 6th, 10th, or 11th house)?

Special Matchers

Pushkara Navamsha: Is the planet in an auspicious navamsha portion?
Gandanta: Is the planet at a water-fire sign junction?
Atmakaraka: Is this the planet with the highest degree (soul significator)?
Yogakaraka: Is this planet a combined kendra-trikona lord?
Functional benefic/malefic: Is this planet functionally benefic or malefic for the specific ascendant?
Hemming (Papakartari/Shubhakartari): Is the house hemmed by malefics or benefics?
Lordship pair: Does the planet rule specific house combinations?

When an indicator’s condition is evaluated against your chart, the relevant matchers fire and return true or false. If the condition is met, the indicator is active for your chart.

Pull and Protect Weights

Each active indicator contributes a pull weight and a protect weight to its target tendency.

Pull weight represents how strongly this condition pushes toward the behavioral tendency. A high pull weight means this planetary condition is a strong contributor to the tendency manifesting.

Protect weight represents how strongly this condition pushes away from the tendency — acting as a buffer, counterbalance, or mitigating factor.

Most indicators have one dominant weight (either pull or protect) and a zero or near-zero opposing weight. Some indicators contribute both — a single planetary condition can simultaneously increase one tendency while decreasing another, or even push and pull on the same tendency with different magnitudes.

Example

Consider the tendency: “Financial risk tolerance”

Active indicators for a hypothetical chart might include:

Indicator	Condition	Pull	Protect
I-127	Mars in the 2nd house	+12	0
I-203	Rahu conjunct 11th lord	+15	0
I-089	Jupiter aspects 2nd house	0	+10
I-342	Saturn in the 2nd in own sign	0	+18
I-156	2nd lord in 8th house	+8	0

Mars in the 2nd house and Rahu conjunct the 11th lord push toward higher risk tolerance. Jupiter’s aspect on the 2nd and Saturn’s strong placement there provide protective counterweights — wisdom and discipline that buffer against reckless risk.

The raw score for this tendency would begin as: (12 + 15 + 8) - (10 + 18) = 35 - 28 = +7 (moderate pull toward financial risk tolerance, partially buffered by protective factors).

The 24 Behavioral Tendencies

Vedtara’s 494 indicators map to 24 behavioral tendencies organized across 5 categories:

Category 1: Drive & Ambition

Career drive intensity
Entrepreneurial disposition
Authority orientation
Competitive instinct

Category 2: Emotional & Relational

Emotional resilience under pressure
Attachment style intensity
Conflict approach (confrontational vs avoidant)
Empathic sensitivity
Partnership dependency

Category 3: Cognitive & Communication

Analytical vs intuitive processing
Communication assertiveness
Learning modality preference
Decision-making speed
Creative expression drive

Category 4: Financial & Material

Financial risk tolerance
Wealth accumulation tendency
Material attachment
Resource management discipline
Generosity disposition

Category 5: Spiritual & Philosophical

Spiritual seeking intensity
Philosophical depth orientation
Dharmic alignment clarity
Detachment capacity
Transcendence readiness

Each tendency is computed independently — all 494 indicators are evaluated against the chart, each active indicator contributes its pull and protect weights to its target tendencies, and each tendency accumulates its own net score.

Phase 1: Natal Baseline

The birth chart is analyzed using all 32 condition matchers against all 494 indicators. Each active indicator deposits its pull and protect weights into the appropriate tendency buckets. The result is a raw score for each of the 24 tendencies — a signed number where positive values indicate net pull toward the tendency and negative values indicate net protection away from it.

This natal baseline represents your static dispositional profile — the behavioral tendencies encoded in the birth chart, independent of time.

Phase 2: Dasha Modulation

The natal baseline is then modulated by the current dasha period. This is where static disposition meets dynamic timing.

For each tendency, Vedtara identifies the key planets — the grahas whose indicators contribute most heavily to that tendency’s score. It then checks whether those planets are activated or suppressed by the currently running dasha.

Activation: If a tendency’s key planet is the current mahadasha lord, antardasha lord, or pratyantardasha lord, the tendency’s score is amplified. The amplification factor depends on the dasha level — mahadasha activation produces up to a 2.0x multiplier, antardasha up to 1.5x, pratyantardasha up to 1.25x. These multipliers stack multiplicatively.

Suppression: If a tendency’s key planet is in a conflicting relationship with the current dasha lord (e.g., natural enemy, or the dasha lord occupies the key planet’s debilitation sign), the score is suppressed — down to 0.5x.

Neutral: If the current dasha has no special relationship with the tendency’s key planets, the score passes through unchanged.

This dasha modulation is what makes Vedtara’s behavioral scores time-sensitive. The same person may score 72 on “entrepreneurial disposition” during a Mars-Rahu dasha period and 45 during a Saturn-Moon period — not because their natal chart changed, but because the dasha system amplifies or suppresses different parts of the natal blueprint at different times.

Phase 3: Transit Adjustment

After dasha modulation, current transits provide a final adjustment layer. Transits are faster-moving than dashas and produce shorter-duration fluctuations.

Vedtara evaluates the current positions of all 9 grahas and their transiting aspects to key chart positions. Each relevant transit contributes a bonus or penalty of up to 15 points to affected tendencies. The 15-point cap ensures that transits modulate scores at the margin rather than overwhelming the natal baseline and dasha structure — which is consistent with classical teaching that transits are the weakest of the three layers (natal > dasha > transit).

Phase 4: Logistic Normalization

The accumulated score — natal baseline + dasha modulation + transit adjustment — passes through a sigmoid (logistic) function that maps the raw score to a 0-100 probability scale.

The sigmoid function has two critical properties:

Bounded output: No matter how extreme the raw score, the final output is always between 0 and 100. This prevents nonsensical values and ensures all tendencies are on a comparable scale.
Diminishing returns at extremes: A raw score of +50 does not produce double the probability of a raw score of +25. The sigmoid curve flattens at the extremes, reflecting the empirical reality that adding more evidence for an already-strong tendency produces diminishing marginal effect. The difference between 70 and 80 on the probability scale requires more incremental evidence than the difference between 40 and 50.

The result is a clean, interpretable score: “Given your natal chart, current dasha period, and active transits, there is a [score]% probability that [tendency] is actively manifesting in your behavioral patterns.”

Why Transparency Matters

Vedtara’s approach to behavioral scoring differs from most astrology platforms in one fundamental way: we show our work.

For every behavioral score, you can drill down to see:

Which indicators are active in your chart
What condition triggered each indicator
The pull and protect weights each indicator contributes
How the dasha modulation affected the score
What transit adjustments are currently active
The raw score before and after normalization

This transparency serves multiple purposes:

Educational Value

Understanding why a score is what it is teaches you astrology far more effectively than simply receiving the score. When you see that your high “entrepreneurial disposition” score comes primarily from Mars in the 10th house aspecting the 1st lord while Rahu conjuncts Mercury in the 11th — and that the current Mars-Mercury antardasha is amplifying both of these indicators — you learn how Vedic astrology actually works.

Calibration and Trust

No behavioral model is perfect. By exposing the indicator-level reasoning, we allow you to evaluate whether the model’s logic resonates with your lived experience. If an indicator seems irrelevant to your life, that observation itself is valuable — it may indicate that other chart factors are overriding it, which is itself an astrological insight.

Intellectual Honesty

Astrology operates in a domain where claims are easy to make and difficult to falsify. Transparency is our response to this challenge. Rather than presenting scores as oracular pronouncements, we present them as computed outputs of a defined model with visible inputs and explicit assumptions. You are then in a position to evaluate the model on its merits rather than accepting or rejecting it on faith.

The Limits of 494 Indicators

No finite set of indicators captures the full complexity of a birth chart. 494 is comprehensive — it covers the major planetary conditions described in classical texts across the most impactful life domains — but it is not exhaustive. The classical literature contains thousands of individual shloka (verses) describing planetary combinations, many of which are highly specific, contradictory across texts, or lack sufficient empirical support for systematic inclusion.

Our indicator set is curated for:

Coverage: All 9 grahas, all 12 houses, all major dignity states, all classical aspect patterns, and all nakshatra-level conditions are represented.
Balance: No single planet or house dominates the indicator count disproportionately.
Source fidelity: Every indicator traces to at least one classical text or systematized practitioner tradition.
Testability: Every indicator’s condition is computationally verifiable — no subjective judgment is required to determine whether a condition is met.

As our understanding deepens and our empirical validation expands, the indicator set will grow. But we will never add indicators for coverage alone — each addition must meet the same curation standards as the original 494.

From Scores to Insight

A probability score is a starting point, not a conclusion. Knowing that your “emotional resilience under pressure” score is 68 tells you something — but the insight emerges from understanding why it is 68, which indicators drive it, which dasha period is currently modulating it, and how it compares to your scores on related tendencies like “conflict approach” and “attachment style intensity.”

Vedtara’s behavioral engine is designed to produce not just numbers but narratives — coherent, compassionate explanations of what the numbers mean in the context of your life. The 494 indicators are the foundation. The scores are the structure. The narrative is the dwelling you actually inhabit.
