युद्धजयार्णवः (योगाः नक्षत्राणि)
हस्त उत्तरभाद्रश्च आर्द्राऽऽषाढा तथैव च ।नष्टार्थाश्चैव दृश्यन्ते सङ्ग्रामो नैव विद्यते ॥ ३२ ॥
In the full Agni Purana this is chapter 126, verse 32.
Hasta, Uttara Bhadrapada, Ardra and Ashadha. Lost things are seen. There is no battle at all.
Simple meaning: Under these nakshatras lost things tend to be found, and no battle takes place.
पुनर्वक्ष्यामि गण्डान्तमृक्षमध्ये यथा स्थितम् ।
Avoid the last 96 minutes of Revati and the first 96 minutes of Ashvini.
उभयोर्याममात्रं तु वर्जयेत्तत्प्रयत्नतः ।
Avoid about three hours at the Revati-Ashvini joint, and about 1.5 hours at Ashlesha-Magha.
द्वितीयं गण्डमाख्यातं तृतीयं भैरवि शृणु ।
The third edge, between Jyeshtha and Moola, is a fierce stretch of time.
