The Supreme Personality of Godhead said: While speaking learned words, you are mourning for what is not worthy of grief. Those who are wise lament neither for the living nor for the dead.
Beginning from this verse the actual discourse of the Bhagavad-gita commences. So far we have witnesses the setting of the scene. In the last few verses Arjuna admits to his inabilities to solve his dilemma on his own and his acceptance of Krishna as his spiritual master. Now that Krishna accepts Arjuna as His disciple, He begins to instruct him in a way to address his confusion. Krishna begins by chastising Arjuna, much as a guru would do to get the complete attention of his disciple. Here Krishna re-iterates the first instruction He gave to Arjuna (in 2.2) that one must never act on the bodily conception but that of the soul. Although Arjuna has spoken according to the niti-sastra (statesmanship) and dharma sastra, he has not taken into consideration the true, basic nature of the soul and the distinction of the body and the soul. Krishna thus calls Arjuna a "fool." Beginning from the next verse, 2.12 till 2.30, Krishna will scientifically explain the distinction between body and soul. This is known as sankhya yoga or the yoga of analysis. This is the only time in the entire Bhagavad-gita that Krishna explains this difference. Never again will He make this point again. The Bhagavad-gita is for those who are committed transcendalists – they are already aware of this distinction. Krishna simply mentions it here in passing for the sake completeness.
