Dear Nitin Sir, you made it abundantly clear that all branches of astrology has it's own merit and own style of calculation..and while we follow a particular style we shouldn't mix it with others..however in cases of house calculation, Parashari system takes lagna as centre and takes 15 degree either side as first house in bhav chalit, but kp takes 30 degree from lagna in anticlock direction as 1st house..don't you agree that this is very basic and whatever branch of Vedic astrology you follow,there shouldn't be difference as far as house calculation involved..you usually give a diplomatic answer on these questions..but we need your point of view on this..
