युद्धजयार्णवः (चक्राणि)
पुनर्मैत्रविभागं तु ताराचक्रं क्रमाच्छृणु ।नामाद्यक्षरमृक्षं तु स्फुटं कृत्वा तु पूर्वतः ॥ १४ ॥
In the full Agni Purana this is chapter 132, verse 14.
Now hear the next one, the tara (star count from the birth nakshatra) chakra, which divides friends, in order. Take the star of the first letter of the name, clearly, from the beginning.
Simple meaning: Now a wheel to find friends is told. Take the star of the first letter of the name.
ऋक्षे तु संस्थितास्तारा नवत्रिका यथाक्रमात् ।
The stars are counted in sets of nine: Janma, Sampat, Vipat, Kshema and the rest.
प्रत्यरा धनदा षष्ठी नैधनामैत्रके परे ।
The nine star counts are named in order. The Janma star count is good.
संपत्तारा महाश्रेष्ठा विपत्तारा तु निष्फला ।
Some star counts give good results and some give none. Pratyara ruins wealth.
