Timeless Wisdom from the Bhagavad Gita

4.41 He who has renounced actions by Yoga, whose doubts are rent asunder by knowledge, and who is self-possessed actions do not bind him, O Arjuna.

योगसंन्यस्तकर्माणं ज्ञानसञ्छिन्नसंशयम् | आत्मवन्तं न कर्माणि निबध्नन्ति धनञ्जय ||४-४१||

4.42 Therefore with the sword of the knowledge (of the Self) cut asunder the doubt of the self born of ignorance, residing in thy heart, and take refuge in Yoga. Arise, O Arjuna.

तस्मादज्ञानसम्भूतं हृत्स्थं ज्ञानासिनात्मनः | छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत ||४-४२||
