भावार्थ:

हे पार्थ! क्या इस (गीताशास्त्र) को तूने एकाग्रचित्त से श्रवण किया? और हे धनञ्जय! क्या तेरा अज्ञानजनित मोह नष्ट हो गया?॥72॥

Translation

English Translation Of Sri Shankaracharya’s Sanskrit Commentary By Swami Gambirananda

18.72 O Partha, kaccit etat, has this that has been said by Me; been srutam, listened to, grasped through hearing; ekagrena, with a none-pointed; cetasa, mind? Or have you been inattentive? O Dhananjaya, kaccit, has; te, your; ajnana-sammohah, delusion caused by ignorance, bewilderment, natural indiscrimination; been pranastah, destroyed, for which purpose has there been this effort on your part for hearing the Scripture, and on My part, the effort of being a teacher?
