Kundali matching is no superstition. Astrology has been proved as a science in the Supreme Court of India and the opposing Scientific communinity lost to Dr KN Rao who proved impecabbly about it.
I agree, that Kundali matching is not the passport to happy life, but dont call it superstitious, it is highly scientific and if you have any doubts in it, consult the Astrology society of India.
