Bhagavad Gita 18.58
Fix your mind on Me, and by My grace you will overcome the obstacles in your path. But if, misled by pride, you do not listen, then you will indeed be lost.
मच्चित्तः सर्वदुर्गाणि मत्प्रसादात्तरिष्यसि।अथ चेत्त्वमहङ्कारान्न श्रोष्यसि विनङ्क्ष्यसि॥maccittaḥ sarvadurgāṇi matprasādāttariṣyasi|atha cettvamahaṅkārānna śroṣyasi vinaṅkṣyasi||
