In the full Agni Purana this is chapter 127, verse 8.
The Moon, Saturn and Mars in the 6th, counted from one's own sign, O Devi, are good. Mercury gives good in the 6th house too. Leave out Jupiter and Venus in the 6th.
Simple meaning: Moon, Saturn, Mars and Mercury in the 6th from the birth sign are good. Jupiter and Venus there are not.
सप्तमोऽर्कः शनिभौमो राहुर्हान्यै सुखाय च ।
In the 7th, Sun, Saturn, Mars and Rahu bring loss; Jupiter, Venus and Mercury bring joy. Mercury and Venus suit the 8th.
शेषा ग्रहास्तथा हान्यै ज्ञभृगू नवमौ शुभौ ।
In the 9th house only Mercury and Venus do well. In the 10th, Venus and the Sun bring gain.
शनिभौमश्च राहुश्च चन्द्रः सौम्यः शुभावहः ।
In the 11th house all planets do well. Jupiter in the 10th house is to be avoided.
