षोडशयोगाध्यायः
अत्र यदींदुः स्वगृहोच्चस्थ इत्यनुवर्त्तते हीनाधिकृतिना त्रिविधाधिकाररहितेन कोर्थः समस्य गृहहद्दाद्रेष्काणनवांशस्थेन लग्नपेन कार्यपेन ॥
Here 'if the Moon is in its own house or uchcha (high point)' carries on from before. 'Hinadhikriti' means one without the three kinds of rank. What does that mean? It means the lagna (rising sign) lord or the lord of the matter stands in a certain place. That place is the house, hadda (a planet's own small part of a sign), drekkana (one-third part of a sign) or navamsha (one-ninth part of a sign) of a neutral planet.
Simple meaning: Best-equal kambula: the Moon is in own or high sign, and the two lords stand in the sign or small parts of a neutral planet.
अत्रोदाहरणे॥
Best-middle kambula example, part 1: Libra rising; Venus in the 10th at 10, in its own small part; Mercury in the 7th.
शक्रांशः १४ स्वीयहद्दायां चंद्रः कर्के नवांशकः ९ ॥
Best-middle kambula example, part 2: Mercury at 14 in its own small part, Moon in Cancer at 9. The result matches the name.
एवं स्वस्वनवांशे तु गतयोर्लग्नकार्ययोः ॥
The same best-middle kambula forms when both lords are in their own navamsha.
