Bhagavad Gita · 18.58

मच्चित्तः सर्वदुर्गाणि मत्प्रसादात्तरिष्यसि।अथ चेत्त्वमहङ्कारान्न श्रोष्यसि विनङ्क्ष्यसि॥

mach-chittaḥ sarva-durgāṇi mat-prasādāt tariṣhyasi atha chet tvam ahaṅkārān na śhroṣhyasi vinaṅkṣhyasi

With your mind fixed on Me, you shall overcome all obstacles by My grace. But if from ego you do not listen, you shall perish.
