आत्मैव ह्यात्मनो बन्धुरात्मैव रिपुरात्मनः।।6.5।।
।।6.5।।अपनेद्वारा अपना उद्धार करे अपना पतन न करे क्योंकि आप ही अपना मित्र है और आप ही अपना शत्रु है।
The word atmana refers to the mind. The mind must detach itself from the infatuation of sense objects by association from those wise in Vedic knowledge who posess spiritual knowledge. In this way the mind will be elevated and gravitate towards spiritual objectives. But if the mind is pointed in the reverse direction subject to worldly pursuits and deluded by sense objects then the mind will become agitated and harassed. Lord Krishna is confirming the truth that the mind has the potential to give the most benefit as the greatest friend to the atma or eternal soul and also that the mind has the potential to be the most destructive as the greatest enemy to the atma or eternal soul depending upon how the mind is influenced.
