Chapter 3 · Name Letters and Chakras
युद्धजयार्णवः (चक्राणि)
सङ्ग्रामे जयमाप्नोति समनामा नरो ध्रुवम् ।अधश्चारे जयं विद्यादूर्ध्वचारे रणे मृतिम् ॥ ११ ॥
In the full Agni Purana this is chapter 133, verse 11.
A man whose name has an even number of letters surely wins in battle. If it moves downward, know it as victory. If it moves upward, it means death in battle.
Simple meaning: An even-lettered name wins in battle. Downward movement brings victory and upward movement death in battle.
शूलखट्वाङ्गहस्तं तु खड्गकट्टारिकोद्यतम् ।
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.
