18.72 O Arjuna! Hast thou listened attentively to My words? Has thy ignorance and thy delusion gone?
Sri Abhinav Gupta
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.
