In Astrology, the trines are 1, 5, 9. From my experience i had learn that if a persons 1, 5, 9 lords are good, they will do well in life, and need not go around to astrologers for readings, more or less they will be self sustained.
Now extending the thought Below is a table that i created, Trines for each of the lord. That is if for 1st Lord, 5th and 9th are trines then For 2nd and 10th.
Quite interesting justification i could discover why 4th lord times play negative especially in transits is the kind of the houses it is associated with (12th and 8th)
Ok, As and when i was writing this article, i thought let me then do the dushatasthana table as. that is 6, 8, 12.
My hunch is that though all these are giving lot of relationships, but im lot at this moment on this topic.
I hope come back to see how these relations manifest in a persons life.
