Chapter 3 · Name Letters and Chakras
युद्धजयार्णवः (चक्राणि)
स्थानसेवा दिवाध्यानं वाणिज्यं राहुदर्शने ।वामनाडीप्रवाहे स्यान्नाम चेद्विषमाक्षरम् ॥ ९ ॥
In the full Agni Purana this is chapter 133, verse 9.
Rahu's turn brings a post in service, daytime brooding and trade. Say the ida (breath through the left nostril) is flowing. And say the name has an odd number of letters:
Simple meaning: Rahu's period brings a post, brooding and trade. Left-nostril breath with an odd-lettered name begins a battle rule.
तदा जयति सङ्ग्रामे शनिभौमस(सु?)सैंहिकाः ।
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.
