there are functional malefics and natural malefics.

1. Natural malefics are krura grahas. These grahas are naturally malefic. Mars, saturn, Rahu and Ketu. Surya is partial malefic. As if mercury(by conj w/natural malefic) and moon(if waning)

2. Functional malefics can be any graha that can turn malefic because of its placement in a particular bhava. It depends on the lagna placement.

example for Aries below:

3. there are three types: 3,6,11(dushtana), 6,8,12(trik) and 3,6,10,11(upachaya)

dustana and trik Bhavas are malefics and 6th is most powerful because it’s Prarabdha karma bhava.

upachaya Bhavas of 3,6,10 and 11 can get better with time.

4. to understand who are the functional malefics for any lagna, start from Aries. For Aries:

trik Bhavas lords are mercury, mars, Ketu and Jupiter for Virgo, Scorpio and Pisces resp.

5. Dushtana Bhava Lords are: mercury, mercury, Saturn, Rahu.

6. upachaya bhava lords are : mercury, mercury, Saturn, Saturn and rahu.

7. Kendras(1,4,7,10) and Trikonas(1,5,9) are powerful functional benefics and can neutralize functional malefics.

8. For Aries, the functional benefics are mars, moon, Saturn, venus. + mars, sun and Jupiter.

9. So functional malefics = mercury, saturn, Rahu, mars, Ketu, Jupiter. Functional benefics: Jupiter, sun, mars, Saturn, moon, venus. Give one point from benefic section to neutralize functional malefics.

10. Resulting in mercury and rahu as functional malefics for Aries lagna charts. They are both upachaya house meaning they will get better in time.

11. Now do the same for all the Lagnas to see for whom Jupiter is functional malefic!
