Nothing is real

In some ways, the words of Sri Krishna reminded me of the film, The Matrix. (haha bear with me)
Arjuna could only become a powerful warrior if he realizes the words of his mentor, Sri Krishna. He must put all fears and feelings of sadness behind him and understand that by fighting, good can come out of it. Krishna tells Arjuna that if he succeeds in battle, he will live on as an honorable man. Should his enemies, or even himself die, they will enjoy the comfort of heaven. It seems to be a win win situation.
It is only when Neo (of the Matrix) puts aside all he thought he knew of his world and realized that none of it was real that he is strong enough to defeat Agent Smith. Neo learns that the world he was once a part of is not real. He is still attached to his old lifestyle and his job. He has commitments and isn't sure if he's ready to joint the life of the all knowing. Once he decides to let go, he begins to learn and discipline himself,, and eventually, he becomes a supreme being, godlike and all knowing.
Arjuna is like Neo. Each man is full of doubt and feels unsure. Neo is apprehensive about leaving his previous world of commitment and selfish desires. Arjuna is in anguish about killing his relatives and friends. The words of Sri Krishna provide answers:
"Selfish desires are consumed in the fire of knowledge"- the more we want to learn, the more we will understand and be better able to make judgements about the world and how to live. Once we figure out why we are attached or feel the need to hold onto things, we can learn to control that want, thus better controlling ourselves.
"2:39 Those who take wisdom as their highest goal, whose faith is deep and whose senses are trained, attain wisdom quickly and enter into perfect peace. 2:40 But the ignorant, indecisive and lacking in faith, waste their lives. They can never be happy in this world or any other."
This passage reminds me how Neo feels he can never be happy now knowing his old life was all based on selfish desires, and the feeling of loss that he can never live in his old life; it will never be the same, but he feels this way he is better off.
A man must remain unperturbed in pain and joy and all things are connected. By accepting things as they are, and feeling no response, we can have a clear mind not clouded by bad judgement or have personal bias for one way or the other. We understand that Krishna is in all things, and by that we are all equal. We are all attached because we are all "precious jewels." Everything is united, and we are all souls born and reborn until we are born unto a state mature enough to seek wisdom.
Krishna says all things are immortal, and if a man is wise, he would not grieve when one life ends;
"2:23, The Self cannot be pierced by weapons or burned by fire; water cannot wet it, nor can wind dry it. 2:24 The Self cannot be pierced or burned, made wet or dry. It is everlasting and infinite, standing on the motionless foundations of eternity. 2:25 The Self is unmanifested, beyond all though, beyond all change. Knowing this, you should not grieve."
The Self Krishna is referring to is what I would equate to having a soul. I find comfort in these passages, as well as 2:27,
"Death is inevitable for the living; birth is inevitable for the dead. Since these are unavoidable, you should not sorrow."
