predicting life after death- death horoscopes.

if the time and date of birth can let us predict the times of life,

then from the time of death we should be able to predict how life after death would be, right?

or at the least, we can assess the past birth, or to be precise, the just finished life.

thereby trying to verify if the actual life experiences and what is seen from 5th house are in sync.

i tried a few death horoscopes of a few people i knew.

the houses i considered were :

5th house(poorvapunnyam)

9th(parapunnyam)

12th(mukthi)

i am confused about a few things, as i haven't found many analyses of the kind.

for eg. if Guru comes into 12th house, is it moksham?

why should we take 12th house, as parapunnyam is clearly mentioned as 9th house?!

in life horoscopes, we say Ketu or Guru in 12th gives more chances for moksham.

i will be happy if it is so, but i found this in both my parent's death horoscopes.

(both were krishna devotees)
