Two charts together: where you meet easily, where you’ll need care
Free marriage compatibility from both birth charts: the matching points the classical books give, Mars placement (Manglik) with what cancels it, and what each chart says about partnership.
How do two birth charts show compatibility?
Indian astrology compares the two birth stars and looks at Mars in both charts, then reads what each chart says about partnership. Some points show where two people meet easily, others where they will need care. No single point decides anything, and a match is never a verdict on two people.
Patri reads what the classical books it uses actually give. The popular 36-point system is not among them, so you will not see a score here: only where the two charts meet easily, and where they will need care.
