Bhagavad Gita 6.34

6. The Path of Meditation

चञ्चलं हि मनः कृष्ण प्रमाथि बलवद्दृढम्। तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम्

chañchalaṁ hi manaḥ kṛiṣhṇa pramāthi balavad dṛiḍham tasyāhaṁ nigrahaṁ manye vāyor iva su-duṣhkaram

For the mind is verily restless, O Krishna; it is impetuous, strong and difficult to bend. I deem it as hard to curb as the wind.
