From what I understand of Bhakti yoga, Arjuna's relationship with Krishna is held as the primary example of devotion as a friend, just as Hanuman's relationship to Ram is the primary example of devotion as a servant. Throughout the conversation, Arjuna and Krishna speak as friends, but there is no doubt that Arjuna reveres Krishna at the same time.
2.9 "When Arjuna the great warrior had thus unburdened his heart, 'I will not fight, Krishna, ' he said, then fell silent."
This statement is quite moving. Arjuna denies his very nature as a warrior, hoping, in his despair, to save those he loves. This is not cowardice, it is love, and concern.
2.10 "Krishna smiled and spoke to Arjuna -- there between the two armies the voice of God spoke these words:'
Imagine the face of your truest friend, radiantly smiling at you! What utter beauty! Then think of the fact that, as Krishna is saying all of this, He is smiling. He is happy to help a friend.
2.11 "Thy tears are for those beyond tears; and are thy words words of wisdom? The wise grieve not for those who live; and they grieve not for those who die -- for life and death shall pass away."
So much is said in this short verse. Arjuna's grief is misplaced because life and death are not at issue here because no one has died or will die. He is caught up in thinking of what may happen, and even if it does happen, it is not worth grieving over. Krishna is asking Arjuna to think in a new way.
2.12 "Because we have been for all time: I and thou, and those kings of men. And we all shall be for all time, for ever and ever.
2.13 As the Spirit of our immortal body wanders on in childhood, and youth, and old age, the Spirit wanders on to a new body: of this the sage has no doubts,"
Outwardly, here is the concept of reincarnation, plain and simple. The soul does not die. Inwardly, a man may go through many trials, but he is still the man he is. If he ceases to despair his life continues anew.
2.14 "From the world of the senses, Arjuna, comes heat and comes cold, and pleasure and pain. They come and go: they are transient. Arise above them, strong soul.
2:15 The man whom these cannot move, whose soul is one, beyond pleasure and pain, is worthy of life in Eternity."
Here lies the possibility of moving beyond the pains and pleasures, and the notion that it is a goal to work toward.
2:16 "The unreal never is: the Real never is not. This truth indeed has been seen by those who can see the true.
What is real? Could it be that what we think is real is not true? The everyday "pains and pleasures" we experience are not real?
