Bhagavad Gita Chapter 2, Verse 60

यततो ह्यपि कौन्तेय पुरुषस्य विपश्चितः । इन्द्रियाणि प्रमाथीनि हरन्ति प्रसभं मनः ॥

yatato hy api kaunteya puruṣasya vipaścitaḥ | indriyāṇi pramāthīni haranti prasabhaṁ manaḥ ||

The turbulent senses, O Arjuna, can violently carry away the mind even of a wise person who is striving.

Krishna delivers a sobering warning: 'yatataḥ api puruṣasya vipaścitaḥ'—even of someone striving ('yatataḥ') and wise ('vipaścitaḥ'), 'indriyāṇi pramāthīni haranti prasabhaṁ manaḥ'—the turbulent ('pramāthīni') senses can forcibly seize ('haranti prasabhaṁ') the mind. This isn't about weak people—it's about the raw power of senses. They don't negotiate; they hijack. Previous verses taught withdrawal (2.58) and transcendence (2.59). Now comes the humbling reality: no technique guarantees immunity. Constant vigilance isn't optional—it's essential.
