The 6th Lord in the 9th House

The 6th lord in the 9th house is the ruler of the 6th, the Ari / Shatru Bhava, placed in the 9th, the Bhagya / Dharma Bhava. The 6th is a dusthana and an upachaya and the 9th a trikona. Which graha that lord is depends on the ascendant, so the table below answers for all twelve.

Counted from the 6th, the 9th is the 4th house, which from any house is a kendra position; counted back from the 9th, the 6th is the 10th, a kendra and an upachaya position from it.

On the Parashari reading, in which a lord carries its house’s matters to wherever it sits, the 6th lord in the 9th reads the 6th’s matters — debts and loans, service and routine, and enemies — through the 9th’s: luck and fortune, father's influence, higher learning, and pilgrimage. For the 6th lord in the 9th that is a frame, not a forecast; what it comes to depends on the graha, its dignity below, and the rest of the chart.

The 6th Lord in the 9th, Ascendant by Ascendant

Across the twelve ascendants the 6th lord in the 9th is exalted for Capricorn, in its own sign for Cancer, in a friend's sign for Taurus, Virgo and Pisces, in a neutral sign for Aries, Gemini and Aquarius, in an enemy's sign for Libra and Sagittarius and debilitated for Leo and Scorpio. The Sun and the Moon rule one sign each, so for Aquarius and Pisces, where one of them is the 6th lord, it rules no other house; for the other ten the last column gives the second house the 6th lord brings with it to the 9th.

For Cancer ascendant the 6th lord, Jupiter, also rules the 9th, so in the 9th it sits in its own other sign, Pisces. For Capricorn ascendant the 6th lord, Mercury, also rules the 9th, so in the 9th it sits in its own other sign, Virgo.

The Reverse: the 9th Lord in the 6th

Where the 9th lord sits in the 6th in the same chart as the 6th lord in the 9th, each lord occupies the other’s sign, an exchange the texts call parivartana. That is possible for ten ascendants. For Cancer (Jupiter) and Capricorn (Mercury) one graha rules both the 6th and the 9th, so there is nothing to exchange.
