Bhagavad-gītā As It Is · Text 6.34
The restless mind
चञ्चलं हि मन: कृष्ण प्रमाथि बलवद्दृढम् ।
तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम् ॥ ३४ ॥
cañcalaṁ hi manaḥ kṛṣṇa
pramāthi balavad dṛḍham
tasyāhaṁ nigrahaṁ manye
vāyor iva su-duṣkaram
The mind is restless, turbulent, obstinate and very strong, O Kṛṣṇa, and to subdue it, I think, is more difficult than controlling the wind.
