कच्चिदेतच्छ्रुतं पार्थ त्वयैकाग्रेण चेतसा।
कच्चिदज्ञानसंमोहः प्रनष्टस्ते धनञ्जय।।18.72।।
18.72. O son of Prtha ! Has this been heared by you with attentive mind ? O Dhananjaya ! Has your strong delusion, born of ignorance, been totally destroyed ?
18.68-72 Ya idam etc. upto Dhananjaya. The very act of explaining this among My devotees is itself an act of cultivating devotion towards Me. Whosoever shall declare etc : Whosoever directs the mind [of the devotees] by face to face method, following the best procedure prescribed in the scriptures; i.e., he who shall impart [this knowledge] - he becomes one with Me. This is an injunction [concerning the result] and not a sentence of praise. Likewise is [the case] in other places also.
