Hayanaratna 3.59

Here, everywhere, within its own deepta degrees (the planet's orb of light), the slow planet may have more degrees than the fast planet. Then the fast planet is the giver of light to the slow one. The slow planet is the taker of light from the fast one. Within the orb, the slow planet may have fewer degrees than the fast planet. Then the fast planet is the taker of the slow one's light. The slow one is the giver. But in the manau (Mars or Saturn blocking the link of two planets) combination, told later, a special line applies. There the slow planet takes the fast one's light, even with more or fewer degrees. This is the point.

Simple meaning: Who gives light: with more degrees the slow planet takes from the fast one. With fewer degrees it gives to the fast one. In manau the slow planet always takes.
