Bhagavad Gita 2.67

इन्द्रियाणां हि चरतां यन्मनोऽनुविधीयते।तदस्य हरति प्रज्ञां वायुर्नावमिवाम्भसि ॥२.६७॥

indriyāṇāṃ hi caratāṃ yanmano’nuvidhīyatetadasya harati prajñāṃ vāyurnāvamivāmbhasi

For the mind, which follows in the wake of the wandering senses, carries away his discrimination, as the wind carries away a boat on the waters.
