प्रव्रज्या सूर्यपुत्रेण राहुणा मूलसंक्षयः ।
The Moon with Saturn may bring renunciation, with Rahu loss at the root, with Ketu lasting hardship.
पापग्रहयुते चन्द्रे दंपत्योर्मरणं भवेत् ।
The Moon with bad planets may put life at risk. With good planets in a strong sign it helps.
दोषायनं भवेल्लग्नं दंपत्योः श्रेयसे सदा ।
With good planets and a strong Moon, the lagna's faults go and it favours the couple.
