Dharm I was taught means property or also duty. Like saltiness is the
property of salt. So 5th and 9th house are property of 1st self. 9th
house is equated to religion for some reason and I feel that that
might be due to the fact that religion teaches one to uphold dharm.
1st 5th and 9th as u said are dharm trikon. for 1st the karak is 8th
so Mars (kalpurush chart), for 5th (leo) its Guru i.e. 8th from 5th
(lord of pisces) and for 9th its moon (cancer) i.e 8th from 9th (sag)
So these are the Moksh sthan and Moksh as I have been taught has got
nothing to do after death but its the ultimate happiness right here in
this life time.
So 4th, i.e 8th from 9th , 12th and 8th house are the karak or say u
can see the End of Dharm, or in other words Moksh achieved.
Means Karak for dharm sthan is Moksh and from Moksh sthan you can time
the end of Dharm or in other words, one reaches Moksh and that is true
happiness and that is the final destination of Dharm.
