बन्धुरात्माऽऽत्मनस्तस्य येनात्मैवात्मना जितः।
अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत्।।6.6।।
।।6.6।।जिसने अपनेआपसे अपनेआपको जीत लिया है उसके लिये आप ही अपना बन्धु है और जिसने अपनेआपको नहीं जीता है ऐसे अनात्माका आत्मा ही शत्रुतामें शत्रुकी तरह बर्ताव करता है।
The mind is only a friend to those who are able to restrain it from flowing externally outwards after sense objects; but if one is unable to subdue the mind that it will harass and aggravate one to satisfy the senses and is the worst enemy. Lord Krishna is conveying that an ungoverned and uncontrolled mind being attached to sense gratification interposes obstructions and deviations in the way which deviates and hinders one from attainment of atma tatva or realisation of the soul. Sage Parasara the father of Vedavyasa has stated that the mind itself is the sole cause of bondage in the material existence as well as the sole cause of moksa or liberation from the material existence. A mind infatuated with desire for sense objects constitutes a state of bondage and a mind free from the delusion of desire for sense objects constitutes the way to moksa. The preliminary competency to be acquired before one commences meditation will be given in the next verse.
