Self-doubt & confidence

क्लैब्यं मा स्म गमः पार्थ नैतत्त्वय्युपपद्यते। क्षुद्रं हृदयदौर्बल्यं त्यक्त्वोत्तिष्ठ परन्तप॥

O Arjuna! Why give way to unmanliness? O thou, who art the terror of thy enemies! Shake off such shameful effeminacy and make ready to act!

Simple meaning

Krishna shakes Arjuna out of his collapse: "Don't give in to this weakness. It doesn't suit you. Shake off this small-heartedness and stand up." Sometimes what we need isn't comfort but a reminder of our own strength.

In real life

उद्धरेदात्मनाऽऽत्मानं नात्मानमवसादयेत्। आत्मैव ह्यात्मनो बन्धुरात्मैव रिपुरात्मनः॥

Let him seek liberation with the help of his Highest Self, and never disgrace his own Self. For that Self is his only friend; yet it can also be his enemy.

Simple meaning

Krishna says: lift yourself up by your own effort and don't put yourself down. Your own mind can be your best friend or your worst enemy.

In real life

बन्धुरात्माऽऽत्मनस्तस्य येनात्मैवात्मना जितः। अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत्॥

To one who has conquered their lower nature with its help, the Self is a friend; but to one who has not done so, it is an enemy.

Simple meaning

Continuing the idea, Krishna says that for someone who has mastered their own mind, the mind becomes a friend. For someone who hasn't, the same mind acts like an enemy.
