The lord of the 6th house in the 3rd house of the horoscope

The ruler of the 6th house in the 3rd house. There will be little or no happiness from close relatives, a cantankerous or bad character, difficulties in fulfilling desires, work as a nanny or a medical profession, an absence of bravery and inspiration, a quick temper, few adventures, diseases of the right ear. The person is indifferent to the arts of music, dance and drama. There are no literary abilities. Sickly brothers and sisters. (James Braha)

The lord of the 6th house in the 3rd house. An irritable person of a very difficult character, having friction with his brothers or with his comrades, resolute but ill-intentioned, possessing skilful hands. (Tom Hopke)

The lord of the 6th house in the 3rd house: prosperous, easily flies into a rage, devoid of courage, inconstant, hostile towards his kin and his subordinates, vindictive, despised by his kin. (Shri G.S. Agarwal)

BPHS 26:63. If the ruler of the 6th bhava is placed in the 3rd bhava, the native will be prone to anger, devoid of bravery, unfriendly towards all his brothers <and sisters> and he will have unruly servants.

Comments: With the Mesha [Aries] and Tula [Libra] Lagnas the ruler of the 6th bhava [house] — Buddha [Mercury] or Guru [Jupiter] respectively — will also be the ruler of the 3rd bhava. The sage Parashara indicated that the ruler of the 3rd bhava occupying the 3rd bhava will give a very good result. Therefore with these Lagnas the results described above will be excellent.
