Uttama (Identical)
Both partners share the same animal yoni. Instincts align without effort — a natural ease of temperament, energy and physical rhythm that needs no negotiation.
Instinctive Harmony • 4 Points
The animal signature of the birth star. Assessing biological and temperamental compatibility to ensure mutual ease, vitality and intimate harmony between partners.
Yoni Koota holds 4 points in the Ashtakoot Milan system. Each of the twenty-seven Nakshatras is assigned one of fourteen animal yonis, and the Nakshatra occupied by the Moon at birth fixes the yoni a person carries for life.
Where Maitri speaks of the mind and Bhakoot of the heart, Yoni speaks of the body and the instincts beneath thought — the pace, appetite and physical temperament a person does not choose. When two yonis agree, private life proceeds with an ease neither partner has to work for.

The Scale of Affinity
Both partners share the same animal yoni. Instincts align without effort — a natural ease of temperament, energy and physical rhythm that needs no negotiation.
The two yonis are amicable or indifferent toward one another. Differences exist but sit well within the range that patience, affection and familiarity resolve over time.
The yonis are natural enemies — Cow and Tiger, Elephant and Lion, Horse and Buffalo, Dog and Deer, Serpent and Mongoose, Cat and Rat, Monkey and Sheep. Instincts pull in opposing directions.

An antagonistic yoni pairing points to a difference in instinct and physical temperament — differing energies, appetites and rhythms of rest. It is a description of the terrain, not a verdict on the marriage.
Yoni carries 4 of the 36 Gunas. Where Nadi and Bhakoot are strong and the Rashi lords are friendly, a weak Yoni score is routinely absorbed by the rest of the chart, and is best read alongside them rather than in isolation.
