Chapter 3 · Name Letters and Chakras
युद्धजयार्णवः (चक्राणि)
तदा जयति सङ्ग्रामे शनिभौमस(सु?)सैंहिकाः ।दक्षनाडीप्रवाहेऽर्के वाणिज्ये(ज्यं) चैव निष्फलम् ॥ १० ॥
In the full Agni Purana this is chapter 133, verse 10.
Then he wins in battle. Saturn, Mars and Rahu, and the Sun when the pingala (breath through the right nostril) flows: trade then bears no fruit. (Our text is unclear here: one letter in the planet list is marked doubtful, so the planets are not certain.)
Simple meaning: Left breath with an odd-lettered name wins battles. With right breath, trade bears no fruit.
सङ्ग्रामे जयमाप्नोति समनामा नरो ध्रुवम् ।
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.
