युद्धजयार्णवः (योगाः नक्षत्राणि)
कोटमध्ये तु या नाडी कथयामि प्रयत्नतः ।मृगश्चाभ्यन्तरे पूर्वं तस्याऽऽग्नेये पुनर्वसुः ॥ ६ ॥
In the full Agni Purana this is chapter 128, verse 6.
Now, with care, I tell the line in the middle of the Kota. Mrigashira is inside, to the east. In its south-east is Punarvasu.
Simple meaning: The inner line starts with Mrigashira in the east and Punarvasu in the south-east.
उत्तरा फल्गुनी याम्ये चित्रा नैर्ऋतसंस्थिता ।
Uttara Phalguni goes south, Chitra south-west, Moola west and Uttara Ashadha north-west.
पूर्वभाद्रपदा सौम्ये रेवती ईशगोचरे ।
Purva Bhadrapada goes north and Revati north-east. The inner line holds eight nakshatras.
आर्द्रा हस्तस्तथाऽऽषाढाचतुष्कं चोत्तरात्रिकम् ।
Ardra, Hasta, Ashadha and an Uttara are the four pillars in the centre of the fort.
