अनागतविधानं तु कर्तव्यं शुभमिच्छता । आपदं शङ्कमानेन पुरुषेण विपश्चिता ॥

— श्रीमद्वाल्मीकिरामायणे अरण्यकाण्डे चतुर्विंश्शस्सर्गः (११ श्लोक)

By observing the evil omen and other clues, ShriRaama assessed the situation well and rightly guessed that Khara-Dushanas would come for war. Hence he made necessarily arrangements for war and took necessary precautions. In this context, ShriRaama spoke this wise verse with Lakshmana:

“One who desires good, must forsee the coming problems and must take necessary precautions.”

Like ShriRaama, we must also be wise and be alert always.
