इन्द्रियाणां हि चरतां यन्मनोऽनुविधीयते। तदस्य हरति प्रज्ञां वायुर्नावमिवाम्भसि॥
indriyanam hi charatam yan mano'nuvidhiyate tad asya harati prajnam vayur navam ivambhasi
Translation
For the mind which follows the wandering senses carries away one's wisdom, as the wind carries a boat on the waters.
Commentary
A vivid image - the mind is like a boat on water, and uncontrolled senses are like strong winds that push it off course. Without the anchor of self-control, even great wisdom can be swept away.
