Shadbala: the six-fold measure of planetary strength
A planet can be well placed and still underdeliver if it is weak. Shadbala is the classical way to put a number on how much power a planet actually has.
Rather than read about it: Shadbala Calculator — computed from your own birth details, on the real ephemeris.
Can a strength come with friction?
You might recognise a capacity in yourself without finding it easy to use. A strength score starts that inquiry; the rest of the chart gives it context.
Computed demonstration, not a person's reading. We used an invented birth input: 12 April 1990, 10:30 in New Delhi, India (28.6139° N, 77.2090° E). The calculation uses Lahiri ayanamsha, whole-sign houses and the historically resolved Asia/Kolkata timezone.
| Computed factor | Example result | What it contributes |
|---|---|---|
| Jupiter's Shadbala | 10.0607 rupas; required minimum 6.5 | Above the engine's planet-specific strength threshold. |
| Jupiter in D1 | Gemini, house 1 | The placement to read alongside its strength. |
| Jupiter in D9 | Capricorn | A different divisional placement to include in the interpretation. |
The reading question: how do these factors work together? The strength value does not establish effortless success, and the D9 position does not erase the strength value. Eternal Evals lets you ask for the connected explanation, then question how well it describes your experience.
These are computed chart facts. No life outcome or personality claim has been inferred about the demonstration input.
Try the question on your own chart
Where does my chart show a capacity that may be difficult to express? Connect the supporting and qualifying factors, and explain the basis for your reading.
Then ask: “Which part of that interpretation is most uncertain?” Or tell it what does not fit and explore the difference.
Inspect your planetary strengths, then use “Continue with this question” to ask the question in your workspace.

What Shadbala is
Shadbala means six strengths. It quantifies a planet's total power by combining six different sources of strength, expressed in a unit called rupas. The required minimum differs by planet; compare the value with that planet's threshold.
It gives the reading a measured strength value. Whether and how that strength helps is a separate question for the whole chart.
The six sources of strength
The six balas are Sthana Bala, positional strength from dignity and placement, Dig Bala, directional strength by house, Kala Bala, temporal strength from time of birth, Cheshta Bala, motional strength, Naisargika Bala, the planet's natural fixed strength, and Drik Bala, strength from aspects.
Each contributes a portion to the total. The reading then considers that strength alongside the planet's role, placement and other chart factors.
Why strength changes the reading
Dignity and Shadbala answer different questions about a planet. Reading them together lets you distinguish a placement's quality from its measured strength, before considering what either means in the whole chart.
Reading dignity and strength together is far more reliable than judging a placement by sign alone.
How Eternal Evals computes Shadbala
Eternal Evals computes the full six-fold Shadbala in rupas for every planet, with the sub-components broken out, and presents it as bars and a radar in the strength view. Because it is computed deterministically, the AI can quote a planet's exact rupa value rather than guessing whether it is strong.
That keeps strength claims grounded: every number traces back to the computed Shadbala.
