Chapter 2, Verse 60
Part of 2: Sānkhya Yog — सांख्ययोगयततो ह्यपि कौन्तेय पुरुषस्य विपश्चितः। इन्द्रियाणि प्रमाथीनि हरन्ति प्रसभं मनः॥
yatato hyapi kaunteya puruṣhasya vipaśhchitaḥ indriyāṇi pramāthīni haranti prasabhaṁ manaḥ
The turbulent senses, O Arjuna, can violently carry away the mind of a wise person, even though they are striving to control them.
The aspirant should first bring the senses under his control. The senses are like horses. If you keep the horses under your perfect control you can reach your destinaton safely. Turbulent horses will throw you down on the way. Even so the turbulent senses will hurl you down into the objects of the senses and you cannot reach your spiritual destination, viz.? Param Dhama (the supreme abode) or the abode of eternal peace and immortality or Moksha (final liberation). (Cf. III.33V.14).
