युद्धजयार्णवः (चक्राणि)
जयस्तस्य सदाकालं सङ्ग्रामे चैव भीषणे ।ह्रस्वनाम(मा) यदा योधो म्रियते ह्यनिवारितः ॥ ५ ॥
In the full Agni Purana this is chapter 131, verse 5.
Victory is his at all times, even in a terrible battle. But when the name is short, the warrior dies, and cannot be saved.
Simple meaning: 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.
पुनश्चान्ते यदा चाऽऽदौ स्वरारूढं तु दृश्यते ।
The verse says the short-named warrior dies in battle and the long-named one wins.
नरचक्रं प्रवक्ष्यामि ह्यृक्षपिण्डात्मकं यथा ।
A wheel is drawn as a human figure and the nakshatras are placed on the body.
