यात्रामण्डलचिन्ता
न कस्यचिद्रिपुर्मित्रं कारणाच्छत्रुमित्रके ।मण्डलं तव संप्रोक्तमेतद्द्वादशराजकम् ॥ २० ॥
In the full Agni Purana this is chapter 233, verse 20.
No one is anyone's enemy or friend by birth. Enemy and friend come about from a cause. The circle has been told to you: it has twelve kings.
Simple meaning: No one is a born enemy or friend. Reasons make them so. The circle has twelve kings.
त्रिविधा रिपवो ज्ञेयाः कुल्यानन्तरकृत्रिमाः ।
There are three kinds of enemy: of the family, next door and made. The first is the hardest.
अनन्तरोऽपि यः शत्रुः सोऽपि मे कृत्रिमो मतः ।
Even a next-door enemy is a made enemy. The enemy has his own friends and enemies too.
पार्ष्णिग्राहमुपायैश्च शमयेच्च तथा स्वकम् ।
Calm the enemy at the rear by the right means. Using a friend to cut down an enemy is praised.
