Chapter 3 · Name Letters and Chakras
युद्धजयार्णवः (चक्राणि)
चैत्रचक्रे तु संस्पर्शाज्जयलाभादिकं विदुः ।विषमे तु शुभं ज्ञेयं समे चाशुभमीरितम् ॥ ३ ॥
In the full Agni Purana this is chapter 131, verse 3.
In the Chaitra chakra, they say gain, victory and the like come from the touch. The odd ones are known as good, and the even ones are called bad.
Simple meaning: In this wheel, odd places bring good results like victory and gain. Even places bring bad results.
युद्धकाले समुत्पन्ने यस्य नाम ह्युदाहृतम् ।
When war begins, look at the person's name and where it sits in the wheel. The sentence ends in the next verse.
जयस्तस्य सदाकालं सङ्ग्रामे चैव भीषणे ।
A good name sitting place brings victory. A short name means the warrior dies in battle.
प्रथमो दीर्घ आदिस्थो द्वितीयो मध्ये अन्तकः(?) ।
A long vowel at the start and others in the middle are read for victory. The rule is not clear.
