यततो ह्यपि कौन्तेय पुरुषस्य विपश्चितः। इन्द्रियाणि प्रमाथीनि हरन्ति प्रसभं मनः॥
yatato hy api kaunteya purushasya vipashchitah indriyani pramathini haranti prasabham manah
Translation
O son of Kunti, the turbulent senses can forcibly carry away the mind even of a discerning person who is striving for self-control.
Commentary
Even wise people who actively practice self-control can be overwhelmed by the powerful senses. Krishna acknowledges the real difficulty of self-mastery, showing that constant vigilance is needed.
