Raja Yoga is the classical combination for power, status, success and rise in life. It forms when the lord of a Kendra (the angular houses 1, 4, 7, 10 - the pillars of the chart) joins forces with the lord of a Trikona (the trines 1, 5, 9 - the houses of fortune and dharma).
How the connection happens
- Conjunction - both lords sit in the same sign.
- Mutual aspect - each lord casts a graha drishti on the other.
- Sign exchange (Parivartana) - each lord sits in the other's sign.
Yogakaraka & Dharma–Karmadhipati
A single planet that rules both a Kendra and a Trikona is a yogakaraka - a Raja Yoga giver on its own (for example Saturn for Taurus/Libra, Mars for Cancer/Leo, Venus for Capricorn/Aquarius). The connection between the 9th lord (dharma) and the 10th lord (karma) is the celebrated Dharma–Karmadhipati Yoga, considered the strongest Raja Yoga of all.
What you get
This calculator lists every Raja Yoga in your chart with the planets and houses involved, the way they connect, a strength grade (from dignity, combustion and placement), the life areas it blesses, the yogakaraka, and the full house-lord table - plus a downloadable PDF.
When does a Raja Yoga fructify?
A Raja Yoga rarely acts from birth. It usually delivers during the Dasha and Antardasha of the planets that form it, and when transits touch those houses. Strong, undamaged lords give a clearer rise; weak, combust or afflicted ones give a milder result that asks for more effort. A yoga whose only dasha window opens before age 12 or after age 85 is not listed here.
This page lists every kendra–trikona link in the chart, with a strength grade. Named cousins isolate one recipe: Dharma–Karmadhipati is the 9th–10th pair, Kendra–Trikona Raja Yoga teaches the general rule, Vipreet Raja Yoga is the reverse geometry from dusthanas, and Jaimini has its own raja yogas from the Karakamsha and Arudha. Presence of several mild links is common; a strong, well-timed one is less so. The Raja Yoga guide names the yoga karaka for each Lagna. The yoga-meaning guide explains why a combination is not a guarantee. A chart describes tendencies. It does not replace work, character or professional advice.
