Good morning somna7h
First of all as per vedic ketu gives the benefits as per which house he sits . ketu in sagittarius is not that much bad .
we have to check rasi for characteristics and house lord for particular event , dont confuse between that . Sagittarius is 9th house of kalapurusha . so ketu spiritual wisdom . person is highly evolved spiritual person , observes religious codes . will undertake many spiritual journeys . also Sagittarius is the own house for ketu so it gives its full 9th power .
but we must also check dispositer lord since it plays major role . but ketu in gurus house is itself very good .
wherever ketu placed in chart person will establish that house related things eg ketu in 11th gives abundant income . ketu in 3rd highly courage . persons leaves a huge impression to others regarding that house .
ketu in 8th , really its not good position in terms of material happiness , except divine wisdom , ketu snatches every happiness from the person , majority of their karma are cleared in the birth itself . seldom they have marital happiness . but they get sex pleasure other than their wife .
constellation also plays major role in this . it said that every dasa gives constellation planet lord results first and then house related things next .
ketu also co owns scorpio ,so whichever house your scorpio falls in ur chart you get that house power too , if you are taurus then scorpio comes as 7th , so along with 8th house you also get 7th house related things too , not to mention your ketu is in 6th lord constellation so it creates conflicts in marriage and health , though you get monetary benefit .
Interesting and least known fact about taurus ascendant is for them first of life is soo good , good health , pretty strong sensual physique , robust health , very active , extraordinary social life . always im in gym . have many admirers and extollers . but sad part is after their marriage their entire life changes completely . reason is before marriage they are in venus control and after marriage they are in guru control , guru is enemy to venus , so whatever venus gave guru will do it opposite . after marriage they entirely dependent on their spouse no matter who it is . their spouse takes in charge of their family and kids . another interesting thing is they are home bound . its ok for girls but boy having taurus asc really suffers for this . they may end up as house husband .
ketu in 4 , 7, 8, 12 not good for material world , person gets repeated blow from every side , ketu teaches that wisdom by wild . he shows that directly , like slapping your face . many sudden untoward event happens in life .
but one thing is that ketu in 8th gives superior spiritual whereas normal person cant even imagine that , trust me , im example for that , i have ketu in 8th as per rasi ( im aquarius rasi) i got superior divine experience and blissful moments ,though it seems like joke or nonsense to materialistic persons ,but what i got is a divine bliss ., only ketu in 8th person knows that . you also have very rare and superior articles on spirituality and religion . also get chance to meet many rare enlightened saints or babas who does many miracles , in calcutta too there lives many babas who perfoms miracles , you may get darshan of those . it all happens in ketu dasa or jupiter dasa .
ketu in 8th , one of the best placement for astrology/astrologers or any fortune tellers ....
for u ketu in 8th as per lagna and as per rasi its in 7th . picture is very clear . except marital happiness you get all . ketu in 7th repeated marriage and breakups , tend towards wrong women for pleasures . mismatched spouse . sensitive touchy wife but spiritual wife . both will be good spiritual pairs rather than sensual lovers ......
