Chapter V
Enemies And Diseases
If the lord of the 8th is in the 1st,
the person will have a sickly body. If the lord of
the 6th is in lagna, he will be troubled by cousins
and diseases.
If the Sun and the Moon are
combined with the lords of the 1st and 6th, the
person will have fear from fever and fear from
water, respectively.
If Mars is with lords of lagna and
6th, the person suffers from wounds, weapons and
plague. If Mercury is similarly disposed, he will
suffer from diseases due to bile.
If Jupiter is similarly conjoined,
the native suffers from no diseases. If Saturn is
similarly combined, he will have fear from thieves
and low class people.
If Rahu and Ketu are in conjunction
with lords of lagna and the 6th, the native
will have fear from reptiles and feline animals.
If Venus is with lords of lagna
and the 6th, danger to wife is shown. If the lord
of the 3rd and Mars join together, he will die
in war.
If the 8th lord is in the 12th in combination with debilitated or inimical planets and the lord of lagna is strong, the person's diseases will all be destroyed.
If lord of lagna, happening also to be lord of the 6th, is weak but is combined with benefic planets, the native's enemies will turn friends.

Commentary & Analysis by B.V. Raman
In this chapter the author briefly deals with diseases and debts. The presence of the 6th lord in lagna is not recommended as also that of the 6th in lagna. In the first case the native will always suffer from disease while in the 2nd instance he will suffer not only from physical diseases but he will be worried due to the machinations of cousins and other relatives. The author has not made any reference to the results that would be produced if Lagna, aspected by the 6th and (or) 8th lords or if lord of lagna is associated with or aspected by these lords. Probably he wants us to anticipate the results.
Danger from fever is indicated, according to stanza 2, if the Sun is in conjunction with both the lord of lagna and the 6th. Similarly, danger from enemies is to be foretold if the 6th and 6th lords are with the Moon. If supposing the 6th lord happens to be either the Sun or the Moon (as
case of Kumbha and Meena Lagnas) then danger from the two sources mentioned above should not be predicted. Similarly, if the 1st and 6th lords are combined with Kuja, there will be danger from wounds, weapons, and agantuka (a disease like plague). If Budha joins the combination of the 1st and 6th lords, the native suffers from bilious trouble. If Guru joins, there will be troubles; if Shani joins the combination, there will be trouble from thieves and low-class persons. If Rahu and Ketu join the combination, the person will have fear from reptiles and danger from feeble genus such as hogs, tigers, etc. If Shukra joins the combination, danger to wife is indicated. The person will die in battle if the third lord joins Kuja (Stanza 6). So far as the combination in stanza 6 is concerned, the student must use much discretion before venturing a prediction. If the third lord happens to be Kuja, then the combination becomes ineffective.
The author stresses the fact that to possess good health, the lord of Lagna should be well placed while the 8th lord should be as weak as possible.
The last stanza is important. According to it, even enemies become friends if Lagnaadhipathi is weak, but happens to be lord of 6th also and is well aspected and conjoined. This is possible in respect of Vrishabha Lagna and Vrischika Lagna as Shukra and Kuja can become lords of Lagna and 6th. The combinations are certainly thought-provoking and give much food for reflective minds.
Thus ends the Fifth Chapter, entitled Enemies and Debts in Bhavartha Ratnakara of Sri Ramanujacharya
