Bhava Bala (House Strength)भाव बल

A strength score for each of the 12 houses themselves (not for individual planets) — combining the strength of the house's own lord, the house's own directional (Dig) strength, and aspects it receives, into one number per house.

In practice

A high Bhava Bala score for, say, the 10th house (career) suggests that house's matters are well-supported overall in this chart, independent of any one planet's individual strength.

How it's calculated

Combines three components into a single per-house total: Bhavadhipati Bala (the house lord's own Shadbala-style strength), Bhava Dig Bala (the directional strength of the house itself, independent of which planets occupy it), and Bhava Drishti Bala (aspectual contributions the house receives).
