उद्धरेदात्मनाऽऽत्मानं नात्मानमवसादयेत्। आत्मैव ह्यात्मनो बन्धुरात्मैव रिपुरात्मनः।।6.5।।
uddhared ātmanātmānaṁ nātmānam avasādayet ātmaiva hyātmano bandhur ātmaiva ripur ātmanaḥ
One should raise oneself by one's own self alone; let not one lower oneself; for the self alone is one's own friend, and the self alone is one's own enemy.
