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

The ruler of the 6th house in the 6th house. The planet is in svakshetra (its own house). Health, good work, victory over enemies, the overcoming of rivals, wealth, an interest in medicine or healing practices, good employees and workers, help from the maternal uncle, the uncle is an outstanding person, help and benefits from cousins. (James Braha)

The lord of the 6th house in the 6th house. This person's uncle is fortunate; a person with such a placement will receive a good opportunity to serve other people, or else he serves in temples. A chance to visit foreign lands will also arise. Abilities in the field of medicine and success in export-import operations are possible. (Tom Hopke)

The lord of the 6th house in the 6th house: a good life span, an absence of illnesses, a healthy body, an average financial position, valour, fame. He is at enmity with those close to him and is friendly with people of another circle. (Shri G.S. Agarwal)

BPHS 26:66. If the ruler of the 6th bhava is placed in the 6th bhava, the native will have enmity with his blood <with some> relatives and friendship with the remaining relatives, and he will obtain only average happiness in matters of wealth and the like.

Comments: The 6th bhava [house] is the bhava of other people, for example of people belonging to other castes (clans, families). Therefore, when the ruler of the 6th bhava is itself placed in the 6th bhava, that is, in its own rashi [sign], the native will be friendly towards other people. Besides this he will possess robust health, will like to take exercise or training, will work hard and will be courageous.
