षोडशयोगाध्यायः
अयमर्थः । परस्परालोकनवर्जितं खेटद्वयं लग्नेशकार्येशाभिधं तृतीयो मंदग्रहः स्वदीप्तांशैर्लग्नाधीशकार्याधीशौ स्थानदृष्ट्या पश्यन् पुनरुभयोर्मध्ये शीघ्रतेजो नीत्वा मंदगाय दत्ते यमयाख्यो योगः स्यात् ॥
The meaning: two planets do not look at each other. They are the lagna (rising sign) lord and the lord of the matter. A third planet, a slow one, looks at both by place with its own deepta degrees (the planet's orb of light). Of the two, it takes the fast one's light and gives it to the slow one. This is the yamaya (a slower planet linking two others) combination.
Simple meaning: Yamaya: the lagna lord and the matter's lord do not see each other. A slow third planet carries light from the fast one to the slow one.
अत्रोदाहरणं संज्ञातन्त्रे ॥
Yamaya example: Venus at 16 in Aries, the Moon at 6 in Taurus, no look between them. Jupiter is the slow third planet.
यमयायोगः
Yamaya chart: Venus at 16 in Aries, the Moon at 6 in Taurus, Jupiter at 10 in Cancer.
दिगंशतः कर्कगतस्तु पश्यन्नुभौ महोदीप्तलवैस्सचान्द्रम् ॥
