Bhagavad Gita 1.30

The bow Gandiva slips from my hand, and my skin burns. I cannot remain still, for my mind is in tumult.

गाण्डीवं स्रंसते हस्तात्त्वक्चैव परिदह्यते।
न च शक्नोम्यवस्थातुं भ्रमतीव च मे मनः॥

gāṇḍīvaṃ sraṃsate hastāttvakcaiva paridahyate|
na ca śaknomyavasthātuṃ bhramatīva ca me manaḥ||
