यात्रामण्डलचिन्ता
प्रतापवृद्धौ तेनापि नामत्राज्जायते भयम् ।यथाऽस्य नोद्विजेल्लोको विश्वासश्च यथा भवेत् ॥ २५ ॥
In the full Agni Purana this is chapter 233, verse 25.
When his power grows by that, no fear comes from an enemy. He should act so the people do not fear him and trust him. (Our text is unclear here: one word is misprinted, and we read it as 'not from an enemy'.)
Simple meaning: When the king wins by his own strength, enemies no longer frighten him. He should keep people calm and trusting.
पार्ष्णिग्राहमुपायैश्च शमयेच्च तथा स्वकम् ।
Calm the enemy at the rear by the right means. Using a friend to cut down an enemy is praised.
मित्रं च शत्रुतामेति सामन्तत्वादनन्तरम् ।
A friend can turn into an enemy. A king who can do it alone should cut down the enemy himself.
जिगीषुर्धर्मविजयी तथा लोकं वशं नयेत् ॥ २६ ॥
A king who wins by dharma should win the people over.
