In the Eleventh Teaching it is conformed that Krishna is a god even more so. So Krishna showed His Cosmic Unversal Form of greatness to Arjuna to prove he is majestic. It describes his form below:
"It was a multiform, wonderous vision,
with countless mouths and eyes
and celestial ornaments,
brandishing many divine weapons."
Why do those few lines prove he is a god? Because in the Hindu culture, the gods usually are full of color and have multiple body parts. Much fuller and bigger proof at last!
Anyways, then Krishna explains to Arjuna how his true form is the original form of the godhead. How his body shows the world's destruction and everything else of and in the world. Then Krishna goes to explain to Arjuna to not be afraid of the battle, because with Arjuna having Krishna on his side, the others were hypothetically already dead. Krishna could not be beaten.
Arjuna feels basically like a nobody standing next to Krishna so he starts to tremble. Arjuna starts apologizing for the way he always acted towards Krishna and for all the things he ever did that he no longer feels was an acceptable action.
In the Twelth Teaching, Krishna tells Arjuna that the worshipping of Krishna, the supreme personality of Godhead, is the best recommadation for worship. So Krishna explains the process of devotion you must have towards him and then Krishna says that anyone who devote to him endearly will be especially dear to him. If you ask me, this Krishna dude is sounding a little full of himself.
The Thirteenth Teaching goes about Arjuna asking about things he wants to learn about and then Krishna answering all of them. Arjuna asks six things which are: nature, the enjoyer, the field of activity, the knower of the field, knowledge, and the object of knowledge. So basically Krishna is having to explain everything again with long examples because Arjuna just can't seem to get anything.
In the Fifteenth Teaching (yes I am skipping fourteen), Krishna is talking about a tree and it's branches. I think this is having something to do with life because of the way he is wording it. Especially when he says "roots are tangled in actions", which I'm taking a guess is referring to men's actions. It even makes it obvious when he says "tree of life." And I'm gussing the branches are all twisted in ways due to people's choices. I also realized that it is possible that it has something to do with Krishna. I think it's saying that all sources of energy and keeping up the universe and all living is Krishna. So Krishna is like the tree.
So hopefully that makes sense.
For the record, John Park should have not been voted off American Idol. The other dude should've gone home. John Park has an amazing voice.
