Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 5 · Omens
शकुनानि
अशस्तो वाद्यशब्दश्च भिन्नभैरवझर्झरः ।एहीति पुरतः शब्दः शस्यते न तु पृष्ठतः ॥ ५ ॥
In the full Agni Purana this is chapter 230, verse 5.
The sound of instruments is not good when it is cracked, fearsome or jarring. The call 'Come!' from in front is praised, but not from behind.
Simple meaning: Cracked or jarring music is bad. A call of 'Come' from the front is good, not from behind.
गच्छेति पश्चाच्छब्दोऽग्र्यः पुरस्तात्तु विगर्हितः ।
'Go' said from behind is best. 'Stay' or 'Where are you going' is bad.
अनिष्टशब्दा मृत्यर्थं क्रव्यादश्च ध्वजादिगः ।
Unwelcome words, a flesh-eating bird on a flag, stumbling mounts or broken weapons can point to death.
शिरोघातश्च हाराद्यैश्छत्रवासादिपातनम् ।
A blow to the head or a falling umbrella is bad. Praying to Hari removes it.
