Aseem,
I don't know in details about guna milap, but from you have said, it does seem to have an important role to play in marriage.
About a manglik marrying a manglik cancelling the dosha, I am not sure how effective that is. I don't feel it has such a strong effect. You have mentioned that 7th house and 7th lord has to be checked, too, for marriage, but I feel--I may come across as prejudiced--Mars in 7th house or 8th house are capable enough to bring problems in marriage, irrespective of how 7th house/lord and Venus are in a chart.
One more thing I would like to say here: you have talked about gun milap and matching of charts in other ways, but if a chart shows bad marriage, wouldn't it give that, irrespective of the matchings done as after all destiny has to give its results. We can't, I think you believe this, too, change our destiny by our free will, and matching charts is just an effort to change the destiny of a marriage, I think you will agree with me here.
deeps wrote:I totally disagree here. Gun milap is very important. Minimum points may not be required but atleast graha maitri, gana, bhakut should be matching so as to avoid conflicts over misunderstandings. Meeting of Minds are very necessary to keep any relationship going on. It is said bhakut dosh is cancelled if graha maitri is there. So that leaves to graha and gana matching.
About PVR, i have not seen his chart. Since He is himself an astrologer, so he must have married a manglik girl to cancel the dosh. Also check how 7th house and 7th Lords are placed.
