The eighth house is Vedic astrology's house of secrecy, transformation, hidden knowledge, sudden events, and joint wealth, while the fourth house governs your mother, home, comfort, and peace of mind. When the fourth house lord moves into the eighth house, you become an intensely private person who finds meaning in hidden or occult subjects, and both your home life and your mother may go through sudden, transformative changes.
If Moon as a Fourth House Lord in the Eighth House:
When Moon rules your fourth house from the eighth, you may have to navigate a transformative relationship with your mother. Moon here sits close to its degree of debilitation, so you could face setbacks connected to property; a benefic aspect or conjunction can soften this influence considerably.
If Sun as a Fourth House Lord in the Eighth House:
Sun as the fourth house lord in the eighth house pushes you toward higher studies and research into occult and philosophical subjects. Because Sun represents your father and the fourth house represents your mother, both parental relationships tend to undergo major changes, and your confidence may take a hit, especially early in life.
If Venus as a Fourth House Lord in the Eighth House:
Venus as the fourth house lord in the eighth house can be debilitated, which tends to make relationships bitter and may cost you part of your family inheritance. You could still build a strong career in research, but secret affairs or infidelity are a real risk to your primary relationship.
If Mercury as a Fourth House Lord in the Eighth House:
Mercury as the fourth house lord in the eighth house makes you a gifted relationship counsellor who can guide others out of troubled partnerships.

If Saturn as a Fourth House Lord in the Eighth House:
Saturn as the fourth house lord in the eighth house points to a strained relationship with your mother and slow growth in both knowledge and marital joint property. Issues with in-laws are likely, but patience pays off, since most of these difficulties ease once you cross the age of thirty.
If Rahu as a Fourth House Lord in the Eighth House:
Rahu as the fourth house lord in the eighth house exchanges qualities with Mercury and leaves you feeling that your occult knowledge is never quite enough, no matter how much you learn.

If Mars as a Fourth House Lord in the Eighth House:
