Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 10 · Yatra and Omens
यात्रा शकुनाश्च
विजयस्तत्र यातॄणां सधिर्वा न पराजयः ।निमित्तशकुनादिभ्यः प्रधानं हि मनोदयः ॥ ६७६ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 676.
Those who march on that day win, or make a truce. They are not defeated. A glad mind counts for more than omens, signs from birds and animals, and the like.
Simple meaning: Marching on Vijaya day brings victory or a truce, never defeat. A glad mind matters more than omens.
तस्मान्मनस्विनां यत्नात्फलहेतुर्मनोदयः ।
A glad mind brings results. Do not set out while a festival, wedding or period of ritual impurity is unfinished.
असमाप्ते न कुर्वीत यात्रां मर्त्यो जिजीविषुः ।
Do not set out during a buffalo-rat fight, a quarrel with your wife or her period.
वस्त्रादेः स्खलिते क्रोधे दुरुक्ते न व्रजेन्नृपः ।
Do not set out after a slip, in anger or after harsh words. Each direction has its food.
