Naisargika Bala

NY-sar-gi-kah BAH-lah

sanskrit: नैसर्गिक बल (Naisargika Bala)

Definition

Naisargika Bala — naisargika meaning natural, bala meaning strength — is the fixed, built-in strength a planet carries from its own brightness, the same in every chart and independent of where it falls. Because it never changes, you don't calculate it chart by chart. It's one of the strengths counted in Shadbala (a six-part strength score), and it works as the tie-breaker: when two planets come out equal in total strength, the one with more Naisargika Bala wins.

In Tradition

The two classical texts that give the full ranking — Brihat Jataka and Saravali — set the seven grahas (planets) in one fixed ascending order of natural strength: Saturn, Mars, Mercury, Jupiter, Venus, Moon, Sun, each naturally stronger than the one before. Brightness is what sets the order, so the Sun, the most luminous, holds the greatest natural strength and Saturn, the darkest, the least.

In Practice

Since the value is the same in every chart, a jyotishi (Vedic astrologer) just applies the fixed figure rather than working it out for each birth, and leans on it mainly as the tie-breaker within Shadbala: when two planets land on an equal total, the one with more Naisargika Bala prevails. To put a number on it, Brihat Parashara Hora Sastra divides one Rupa (a strength unit) by seven and multiplies by one through seven, giving the Sun the maximum of 1.000 Rupa and Saturn the minimum of 0.143 Rupa. Charak runs the same derivation in Shashtyamshas (sixtieths), with the Sun at 60 and Saturn at about 8.57. Raman lists the order strongest to weakest as Sun, Moon, Venus, Jupiter, Mercury, Mars, Saturn — Sun still highest, Saturn still lowest, but the middle differs from the classical sequence.

Historical Origin

Naisargika Bala is attested in the classical Jyotish texts. Brihat Jataka (Varahamihira, Ch.II Sl.21) and Saravali (Kalyana Varma, Ch.4 Sl.40) both give the fixed ranking, while Brihat Parashara Hora Sastra (Ch.27 Sl.14) supplies its numerical derivation and its tie-breaker use. Modern authors including Charak, Kannan, and Raman restate it.
