Cancer and Capricorn Compatibility

Cancer and Capricorn are Karka and Makara, opposite signs, both chara, one ruled by the Moon and the other by Saturn. Jupiter is exalted in Karka. Mars is exalted in Makara. Those exaltations would be false if the pair were Leo and Aquarius, where the Sun and Saturn rule and no such exaltations sit. If one person has Karka lagna and the other has Makara lagna, each rising sign falls in the other's 7th house. That is a real synastry fact about the marriage axis. It does not score love, and it does not score a sexual life. Opposite Moon signs are a 1/7 bhakoot relationship, and 1/7 is not the bhakoot dosha. The dosha is 6/8 and 2/12. Calling this pair incompatible because they are opposites uses the wrong kuta rule.

Attraction and courtship are the 5th house. Marriage is the 7th and D9. Intimacy, the part of the question that is about sex, is the 8th house, not a paragraph of techniques. For Karka lagna the 8th is Kumbha, ruled by Saturn. For Makara lagna the 8th is Simha, ruled by the Sun. A couple whose lagnas are these two signs therefore carry different 8th lords, Sun and Saturn, who are enemies. That can describe a private life with mismatched tempos, one warmer and more visible, one slower and more reserved. It can also be irrelevant if the 8th lords are well placed. Nothing in the sign pair predicts a good or bad sexual bond for every Cancer-Capricorn couple, because most people asking are using sun signs, and sun signs are not lagnas.

If the Moons themselves are in Karka and Makara, guna milan still runs all eight kootas, with Nadi worth 8 points and Bhakoot worth 7. The opposite signs do not automatically fail Bhakoot. They can still fail Nadi if both nakshatras share Adi, Madhya, or Antya. They can still fail Graha Maitri because the Moon and Saturn are not friends. Saturn is an enemy of the Moon's camp in the usual friendship table: Saturn's enemies include the Sun and the Moon. A pretty opposition is not a free match. Both 7th lords and both Navamshas remain the marriage reading after the points are counted. A high score with a broken 7th lord is not a love story. A modest score with strong 7th lords is not a rejection.
