Bhagavad Gita 4.42
Therefore, cleave asunder with the sword of wisdom the doubts of the heart, which your own ignorance has engendered, and follow the path of wisdom and arise!
तस्मादज्ञानसंभूतं हृत्स्थं ज्ञानासिनाऽऽत्मनः।
छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत॥tasmādajñānasaṃbhūtaṃ hṛtsthaṃ jñānāsinā''tmanaḥ|
chittvainaṃ saṃśayaṃ yogamātiṣṭhottiṣṭha bhārata||
