The dasha opens, the transit fires
The governing relationship: the dasha grants permission for the matters its lords significate; the transit activates them in real time. An event needs both — the door open (dasha) and something walking through it (transit). Read them as one system with two roles, never in isolation.
A marriage-permitting dasha waits for a transit on the 7th to actually fire the wedding.
The workflow
Promise, window, trigger, narrow
The reading sequence for 'when will X happen': (1) confirm the natal PROMISE (modules 4-7); (2) find the dasha WINDOWS whose lords significate X (n77); (3) within them, find the TRANSIT — slow-planet or double transit (n84) — activating X's house or lord; (4) NARROW with the pratyantardasha and faster transits. Four steps, always in that order.
First the promise, then the dasha years, then the transit season inside them.
When the two disagree, the dasha wins
If the dasha and transit conflict, the DASHA wins — permission outranks trigger. A brilliant transit in a dasha that denies the matter mostly misfires; a supportive dasha with no current transit merely waits for one. Read the dasha as primary and the transit as its timing agent, not its equal.
A great transit on the 7th during a dasha hostile to marriage rarely delivers a marriage.
When trigger echoes permission
Some triggers are unusually potent: when the transiting planet IS the dasha lord, or transits over the dasha lord's natal position, permission and trigger resonate on the same planet. These 'as-above-so-below' alignments are among the most reliable event-timers in practice.
A Jupiter dasha with Jupiter transiting the natal Jupiter is a strongly lit window.
Worked case — the promise
Arjun's promotion: is a career even promised?
Arjun, Libra lagna. Career is the 10th (Cancer); its lord is the Moon, sitting in the 8th. His yogakaraka Saturn (own-sign Capricorn, 4th house) aspects the 10th by its 7th glance, and his 10th holds the chart's strongest Ashtakavarga (SAV 37). Verdict: career is strongly promised — step one clears.
10th lord Moon, yogakaraka Saturn aspecting the 10th, SAV 37 — a rich, promised career.
Worked case — window and trigger
The dasha door, then the slow sky
Window: his Jupiter mahadasha (33.6-49.6) reaches its Saturn antardasha at 35.7-38.2 — and Saturn is his yogakaraka, so this AD carries the career. Trigger: state the slow sky as Jupiter in Taurus, Saturn in Pisces. Taurus is his 8th HOUSE (from the lagna) and the seat of his Moon — the 10th lord; counted from the Moon it is the 1st. Jupiter sits there and Saturn's 3rd aspect (Pisces to Taurus) reaches it: a double transit on the 10th LORD.
Jupiter over the Moon (the 10th lord) with Saturn aspecting it — opportunity and permanence on the career-lord, inside the yogakaraka's AD.
Worked case — narrow and speak
To a season, honestly framed
Narrow: within Saturn's AD (35.7-38.2), the pratyantardasha and faster transits (the Sun or Mars crossing the 10th lord) mark a season near 36-37 as the sharpest. Speak it as a strong likelihood, not a certainty: the method raises confidence, but it is capped by birth-time accuracy (n78) and never overrides the promise. 'A real elevation is likely around 36-37; here is the window and its limit.'
Promise cleared, yogakaraka AD open, double transit on the 10th lord, narrowed to a season — a confident, honest call.
The one idea to keep
Door from the dasha, key turned by the transit
Timing is one method with two clocks: confirm the promise, open the dasha window, fire it with a transit, narrow with the beat — the dasha winning any conflict, and firmest when the trigger echoes the permission. Promise, window, trigger, narrow.
