The lord of the 6th house in the 8th house of the horoscope

The ruler of the 6th house in the 8th house. Ill health, chronic diseases, poor occupations, strong enemies or envious people, bad employees, dishonest workers, losses because of subordinates, the middle of life is hazy and confused, no material help from the marriage partner, no income from wills or insurance policies. (James Braha)

The lord of the 6th house in the 8th house. An average life span, periods of failure in business, other people will deceive them or get the better of them in something. Debts, bad company. (Tom Hopke)

The lord of the 6th house in the 8th house: an unhealthy body, a dubious personality, covetous of other people's money and women, immoral, vile, quarrels with everyone. (Shri G.S. Agarwal)

BPHS 26:68. In the case of the ruler of the 6th bhava falling into the 8th bhava, the native will be sickly, will be hostile towards knowledgeable and wise people, will desire to obtain other people's wealth, will be interested in other men's wives and he will have dirty or vulgar thoughts.

Comments: The placement of the ruler of the 6th bhava [house] in the 8th bhava gives the native such an illness as lasts throughout his whole life and in the end also becomes the cause of his death. The conjunction of the ruler of the 6th bhava with the ruler of the 8th bhava and Shani [Saturn] will be even more ruinous. The ruler of the 6th bhava is an indicator of unfavourable results. When it is placed in the 8th bhava, these unfavourable results will be destroyed and Viparita Raja yoga is created, which will give the native wealth, property and other favourable results.
