how to decide is rahu/ketu benefic/malefic in a horoscope?

[Guest guest]

Hi,this is what i know abt rahu/ketu :

Rahu is said to be strong, when posited in Mesh, Vrishabh, Kark,

Vrischik, or Kumbh, or, when yuti with Surya, or Candr, during

Parivesh and at the end of a Rasi i. e., when he starts his journey

in a Rasi.

 

Rahu is strong in Mesh, Kanya, Vrishabh, Vrischik and Kumbh. He is

also strong in Karm Bhava. (Jataka Parijata Ch. II),For Rahu, Taurus

is the place of exaltation, Gemini and Cancer are moolatrikonas

 

Ketu has strength in the second portion of Dhanu. He is also strong

in Meen, Kanya and Vrishabh and in night, or, when a rainbow, or a

meteor is noticed.

 

For Ketu, Pisces is own house, Libra friendly, Aquarius own house,

Scorpio the place of exaltation, and Sagittarius and Capricorn the

moolatrikona places

 

BUT

what are the houses of rahu/ketu debeliation?

in which houses(1,2,3---- 12) rahu/ketu are beneficial?

in which houses they are malefic?
