Very useful Shloka's

1. To overcome fear of Snakes:
सर्पापसर्पा भद्रं ते गच्छ सर्प महाविष
जनमेजय यज्ञांते आस्तीक वचनं स्मर ।
[ O poisonous snake, please go away from here. You recall the promise made by your ancestors to sage Astheeka]
Sage Astheeka was instrumental in stopping the Sarpa Yagna of Janamejaya. In gratitude, all snakes promised the sage not to to hurt anyone who remembers him.

2. To find lost items:
कार्तावीर्यार्जुन: नाम राजा बाहू सहस्रावान्
यस्य स्मरण मात्रेण गतं नष्टं च लभ्यते ।
[If you remember Kaarthaveeryaarjuna, a king with 1000 hands, you will easily get lost items].
