तस्मादज्ञानसंभूतं हृत्स्थं ज्ञानासिनाऽऽत्मनः।
छित्त्वैनं संशयं योगमातिष्ठोत्तिष्ठ भारत।।4.42।।
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.
4.42 Tasmat, therefore, O scion of the Bharata dynasty; atistha, take recourse to, i.e. undertake; yogam, yoga -performance of actions, which is a means to full Illumination; and now, uttistha, rise up for battle; chittva, cutting asunder; jnanasina, with the sword of Knowledge-Knowledge is full Illumination, which is a destroyer of such defects as sorrows, delusion, etc.; that itself is the sword; with that sword of Knowledge-;enam, this; samsayam, doubt; atmanah, of your own, which is a source of ones own ruin and is most sinful; hrtstham, in the heart, residing in the intellect; ajnana-sambhutam, arising from ignorance, born of non-discrimination. The word atmanah is used because doubt concerns oneself. Indeed, anothers doubt cannot be removed by someone else. Hence the word own is used. So, although the doubt is with regard to the Self, it is really ones own.
