Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Atma-Samyama Yoga Chapter 6, Verse 6.5.
उद्धरेदात्मनात्मानं नात्मानमवसादयेत् । आत्मैव ह्यात्मनो बन्धुरात्मैव रिपुरात्मनः ॥ ६.५ ॥
अपने द्वारा अपना संसार- समुद्रसे उद्धार करे और अपनेको अधोगतिमें न डाले; क्योंकि यह मनुष्य आप ही तो अपना मित्र है और आप ही अपना शत्रु है|
Dear Arjuna, one should lift himself through his own efforts. He success or failure in performing his Karma should be the result of his own doing. Should a man fail, he should not degrade himself, O Arjuna, for he is his own true friend as well as his own true enemy.
