The 10th Lord in the 4th House

The 10th lord in the 4th house is the ruler of the 10th, the Karma Bhava, placed in the 4th, the Sukha Bhava. The 10th is a kendra and an upachaya and the 4th a kendra. Which graha that lord is depends on the ascendant, so the table below answers for all twelve.

Counted from the 10th, the 4th is the 7th house, which from any house is a kendra position; counted back from the 4th, the 10th is the 7th, a kendra position from it. The 10th and the 4th face each other across the chart, so the 10th lord in the 4th aspects its own house with the 7th-house drishti every graha casts.

On the Parashari reading, in which a lord carries its house’s matters to wherever it sits, the 10th lord in the 4th reads the 10th’s matters — career and profession, public reputation, authority, and achievements — through the 4th’s: mother's influence, home and property, inner contentment, and vehicles. For the 10th lord in the 4th 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 10th Lord in the 4th, Ascendant by Ascendant

Across the twelve ascendants the 10th lord in the 4th is in a neutral sign for Cancer, Leo, Virgo, Libra, Capricorn and Aquarius, in an enemy's sign for Aries, Taurus, Gemini, Scorpio and Pisces and debilitated for Sagittarius. The Sun and the Moon rule one sign each, so for Libra and Scorpio, where one of them is the 10th lord, it rules no other house; for the other ten the last column gives the second house the 10th lord brings with it to the 4th.

For Taurus ascendant (Saturn, ruling the 9th and 10th), Cancer ascendant (Mars, ruling the 5th and 10th) and Capricorn ascendant (Venus, ruling the 5th and 10th), the 10th lord rules both a kendra and a trikona other than the 1st, and in the 4th it is in an enemy's sign for Taurus, in a neutral sign for Cancer and in a neutral sign for Capricorn.

The Reverse: the 4th Lord in the 10th

Where the 4th lord sits in the 10th in the same chart as the 10th lord in the 4th, each lord occupies the other’s sign, an exchange the texts call parivartana. For all twelve ascendants the 10th and the 4th have different lords, so the exchange is possible whatever the ascendant.
