Yoni koota
Yoni koota is the fourth Guna Milan factor, worth 4 points. Each nakshatra has an animal symbol (yoni), and comparing the two animals shows physical and instinctive compatibility.
Also known as: Yoni kuta, Yoni milan, Yoni porutham, yoni guna
The 27 nakshatras share 14 animals, each in a male and a female form: horse, elephant, sheep, serpent, dog, cat, rat, cow, buffalo, tiger, deer, monkey, mongoose and lion. Ashwini’s yoni is the horse, for example, and Rohini’s the serpent.
The same animal scores the full 4 points, friendly animals 2 or 3, unfriendly ones 1, and natural enemies 0. The seven enemy pairs are horse and buffalo, elephant and lion, sheep and monkey, serpent and mongoose, dog and deer, cat and rat, and cow and tiger.
Yoni is read as physical comfort, intimacy and instinctive understanding between partners. It is one factor among eight, and astrologers also look at the 7th house and Venus for the same themes.
