युद्धजयार्णवः (चक्राणि)
शूलखट्वाङ्गहस्तं तु खड्गकट्टारिकोद्यतम् ।भक्षणं(कं) परसैन्यानामात्मसैन्यपराङ्मुखम् ॥ १४ ॥
In the full Agni Purana this is chapter 133, verse 14.
Picture a figure with a spear and a skull-topped staff in hand. He raises a sword and a dagger. He eats up the enemy's armies. His face is turned away from his own army.
Simple meaning: This describes a fierce figure with weapons that devours the enemy armies and turns away from its own.
संमुखं शत्रुसैन्यस्य शतमष्टोत्तरं जपेत् ।
Picture the figure facing the enemy and chant 108 times. At the drum sound, the enemy drops weapons and runs.
परसैन्यं(न्ये) शृणु भङ्गं प्रयोगेण पुनर्वदे ।
This is a rite to break the enemy army. Take cremation-ground charcoal and owl and crow droppings.
कर्पटे प्रतिमां लिख्य साध्यस्यैवाक्षरं यथा ।
Draw a figure on cloth, with the target's name in it. Write the enemy's name nine times.
