In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 684.
Then fish with rice, mixed rice, and curd rice. These go in order from Ashvini. Having eaten the food of the day's star, the king sets out with elephants, horses, chariots and men. He beats his enemies.
Simple meaning: Each star from Ashvini has its food. Eating it, the king marches with his army and beats his foes.
कार्यं निगमनं छत्रे ध्वजशस्त्रास्त्रवाहनैः ।
Go out with umbrella, banner, weapons and vehicles. The leaving place is two hundred dandas from home.
चत्वारिंशद्वादशैव प्रस्थितः स स्वयं गतः ।
Sending your things ahead counts as setting out. Do not then stay a week in one place.
पंचरात्रं च पुरतः पुनर्लग्नांतरे व्रजेत् ।
After a halt of five nights, he can go again in another lagna. Do not go in unseasonal storms.
