युद्धजयार्णवः (चक्राणि)
शुक्ले त्यजेत्कुजगुणान्धाद्या मान्ताश्च पूर्वतः ।याद्या हान्ता उत्तरे स्युस्तिथिदृष्टिं विवर्जयेत् ॥ १२ ॥
In the full Agni Purana this is chapter 142, verse 12.
In the bright half, avoid the kujagunas. The letters from dha to ma are in the east. The letters from ya to ha are in the north. Avoid the look of the Rahu of the tithi (moon day). (Our text is unclear here: the word kujaguna is not clear.)
Simple meaning: In the bright half, avoid certain things. Letters are set in the east and north. Avoid the look of the moon day.
पूर्वाश्च दक्षिणास्तिस्रो रेखा वै मूलभेदके ।
Draw three lines each way. Write the signs from the Sun's sign. Under the look, loss; otherwise victory.
विष्टिराहुं प्रवक्ष्यामि अष्टौ रेखास्तु पातयेत् ।
Vishti Rahu uses eight lines moving round the directions from the north-east to the south, north-west, east and west.
नैर्ऋताच्च नयेच्चन्द्रं चन्द्रादग्निं ततो जले ।
Rahu with Vishti goes round the directions from the south-west through the north and south-east to the west and north-east.
