BHAVAGAD-GITA -- THE THIRD, FOURTH, AND FIFTH TEACHINGS Life Lessons from a Charioteer

What I want to understand is why someone who seems to be so powerful and so wise as Arjuna takes advice given by his charioteer, Krishna, so seriously. How do we even know if Krishna knows about this subject, how did he become the one with all the answers all of a sudden?
I also want to know what Krishna's point is. He has gone over so many, coming back to them and moving on, that I don't understand what he is telling Arjuna to do. First he tells him about reincarnation, that ' the embodied self is enduring' and killing won't make a difference. Then he talks about the detachment from all his emotion, to be in control. He also says that he should do actions 'freed from attachment'. The next idea he speaks of is sacrifice, 'freed from attachment,... preform[ing] action as sacrifice', he says that to do this we need 'understanding' and 'discipline'. He then goes back to the detachment of feelings and especially of desire. I think he is finally telling Arjuna that he should go on with the battle, 'perfom action[s]' but without feeling anything towards it.

We now find that Krishna is, or at least, describes himself as a kind of god. He 'protect[s] men of virtue and destroy[s] men who do evil', he is the one ho teaches what is right and what is wrong, and everybody comes to seek his advice. He says that he remembers his past lives and that he has advised even the sun itself, although this gives him a lot more credential, I think it is very pretentious of him. Lord Krishna is still saying how Arjuna must need to have discipline and to do actions without any emotions, but at the same time he is contradicting himself by saying that disciplined men, and men who understand, must make sacrifices by knowledge and not by actions. I still cannot see what Krishna's point is, and I doubt Arjuna sees it either.

In fact, Arjuna is kind of confused about what Krishna is saying, and he says 'you praise renunciation of actions and then discipline; tell me with certainty which is the better of these two'. I think Krishna is saying that one must first dettach from one's emotions, although I find implied that we must only dettach from our evil emotions and not the peaceful ones, then one will obtain discipline and then one must renuonce from actions. From this will come knowledge, and we will 'ha[ve] joy, delight, and light within... the pure calm of infinity'. I find this very similar to what many religions, for example, Catholisism, tells you today. They tell you to clean yourself of evil emotions, evil thoughts, and sins and then the peace and heaven will come. This is yet another link I find from this book to ancient religions.
