As you know already, functional malefic planets are those lording over bad houses such as 6th, 8th, and 12th. 3rd house is both good and bad as it is 8th to 8th.
If a functional malefic planet is in good house, it spoils the good effects of the good house in which it is situated. Again, it increases the bad effects of the bad house for which it is the lord.
For example, 6th lord is in 9th house. If you take Libra as the Lagna, sixth lord is Jupiter and its presence in 9th house that is Gemini spoils the 9th house. How? 9th house is luck, father, higher studies as it is 5th to fifth, and religious and spiritual matters. As sixth house lord, it spoils the effects of the ninth house. There may be obstacles in pursuing the higher education of the native. As sixth lord represents sickness, father may fall sick. Ninth represents long distance travels and sixth represents foreign elements too. There may be problems with the association of new people.
In this way you have to analyse. The second effect is that as I told you the bad effects of sixth house would increase. How? Sixth represents sickness, debts and anxiety, service problems, legal problems and so on. As a result, the native may fall into a debt trap. Because of useless long distance travels, the native may waste away money and feel exhausted and buy problems. There may be service problems for the native. If there is powerful sickness yoga in the horoscope, the native may fall sick in the sub or sub – sub periods of the sixth lord.
You have to understand that the events or issues relating to the two houses, in this case 6th and 9th houses would take place during the periods of concerned planets.
Functional malefic planets in a bad / malefic house:
A functional malefic planet in a bad house is always good. The reason is that the functional malefic planet destroys the bad effects of the bad house in which it is present. It also destroys the bad effects of the house for which it is the lord.
For example, 6th house lord Jupiter is in 12th house in Virgo for a native of Tula (Libra)
Being a functional malefic, Jupiter destroys the bad effects of 12th house. Again, being situated in a bad house, it weakens itself and destroys the bad effects of its house that is sixth house. As two houses representing bad characteristics are destroyed, some good things would happen and the effect is known as the Vipareet Raja Yoga.
In this example, during the sub or sub-sub periods of Jupiter, native may recover from illness. He / she may pay off the debts all of a sudden. An unemployed native may suddenly get a job like PV Narasimha Rao who became PM during such a period. A native staying at a long distance place away from home may suddenly get a transfer and be posted at his / her native place. Like this, some good developments may take place giving relief to the native.
You must remember that during such periods, things would take place suddenly.
