The lord of the 6th house in the 4th house of the horoscope

The ruler of the 6th house in the 4th house. Disagreements with the mother, a sickly mother. Difficulties with land, the home or means of transport. Problems with cars, little luxury and comfort in life, interruptions in education, difficulty in obtaining an academic degree, a difficult completion of affairs, sickliness at the end of life, little or no inherited
property, and also little immovable property. (James Braha)

The lord of the 6th house in the 4th house. An unstable character, frequent changes of place; this person is the cause of one trouble or another for the people who come into contact with him. A lack of love in relations with the mother, poor surroundings, a weak heart and chest are possible. (Tom Hopke)

The lord of the 6th house in the 4th house: jealous, problems with the mother, profit from the maternal uncle. (Shri G.S. Agarwal)

BPHS 26:64. In the case where the ruler of the 6th bhava is placed in the 4th bhava, the native will be deprived of the happiness of a mother, will become a gossip, will be intelligent, jealous, inconstant of mind and very wealthy.

Comments: A native with this combination is in danger of an accident involving a vehicle. Disputes over immovable property may arise. There are always some disagreements on the question of property. Such a person will be drawn into some public disputes. Those born with the Tula [Libra] Lagna receive unfavourable or ruinous results with regard to the property inherited from the mother. Some accident is an indisputable fact.
