Strength drawn from the clock
Kala bala — kala, time — scores the birth moment itself, and its headline sub-rule is natonnata, the day-night split: the Moon, Mars, and Saturn are strong in night births; the Sun, Jupiter, and Venus in day births; Mercury is strong in both. The hour you arrived is itself a source of strength.
A 2 a.m. birth hands the Moon, Mars, and Saturn their day-night credit before a single house is read. Flip the same chart to 2 p.m. and the credit walks across to the Sun, Jupiter, and Venus.
Paksha, lords, and the solstice
The bundle keeps going. Paksha bala quantifies lesson 13's phase rule: the waxing Moon strengthens benefics, the waning strengthens malefics. Then come credits for the lords of the birth year, month, weekday, and hora — the planetary hour — plus ayana bala from the Sun's solstice position. Moment-of-birth bookkeeping; software sums it, you name it.
A benefic in a bright-fortnight chart quietly banks paksha bala — the phase rule you learned qualitatively, now paying in virupas.
Retrograde means strong, not broken
Cheshta bala — cheshta, effort — pays for apparent motion. A retrograde planet earns high cheshta bala: backward motion against the sky reads as vigorous, insistent effort. Fast direct motion earns less. The Sun and Moon never retrograde, so they take motional credit differently — the Sun through ayana, the Moon through paksha.
Lesson 25's teaser, now with a number: retrograde Saturn posts a fat cheshta score — the planet everyone calls slow, suddenly the hardest worker in the ledger.
The fixed rank, by brightness
Naisargika bala — natural strength — is the only fixed component: identical in every chart ever cast. It ranks the planets by brightness, descending: Sun, Moon, Venus, Jupiter, Mercury, Mars, Saturn. Its job is tie-breaking. Note the irony — Saturn, permanently last, still dominates charts through the other five columns. The fixed rank is the weakest voice.
Two planets dead level after five columns: the brighter one edges ahead. That is all naisargika ever decides.
The net of every glance
Drik bala — drik, sight — nets out module 3's aspect map. Aspects received from benefics add strength; from malefics, subtract. Each glance is weighted by aspect closeness — quarter, half, three-quarter, or full. A planet under heavy malefic glances runs with weights on its ankles; under benefic glances it runs supported.
Venus taking full aspects from Saturn and Mars, with no benefic watching, posts a negative drik bala — strength subtracted before she even acts.
The full ledger, and who can see what
Sthana plus dig plus kala plus cheshta plus naisargika plus drik: that sum faces lesson 38's minimum-rupa bar. The eyeball split: sthana and dig you read from the wheel; kala and cheshta need the exact birth data; naisargika you memorize; drik needs the full aspect map. Two visible columns, four hidden ones.
A planet that looked strong on the wheel but failed its bar usually bled in the hidden four — a day birth for a night planet, sluggish direct motion, malefic glances.
The one idea to keep
Know what moved the number
Time, motion, nature, and glances — the four strengths you cannot see on the chart wheel alone. Let the software sum them; your job is to know what moved the number. When a total surprises you, interrogate the columns in order: hour, motion, rank, gazes — one of them always confesses.
