The most commonly used system for kundali matching is the Ashtakoota system, which divides the 36 gunas into eight main categories, each associated with different aspects of life. These categories include factors like Varna (social compatibility), Vashya (mutual attraction), Tara (health compatibility), Yoni (sexual compatibility), Graha Maitri (mental compatibility), Gana (temperament compatibility), Bhakoot (emotional compatibility), and Nadi (health and progeny compatibility).
