Believing that if we do bad things in our life may make us re-birth as an animal is very interesting? I don't see here why to them being an animal is so bad. What does the animal symbolize to them?
If something is going on in this world, it means that some system stands necessarily behind this,
Here they are saying, in simpler terms, that everything has a force. Everything that happens in the world is made by some "system" which is behind it. So, this is saying that things can and will happen no matter what, confirming their belief in fate.
It begins to talk about Karma here, however this was not the assignment it is still interesting. What they say about Karma is that man needs to be aware of the mistakes that they have made and try to fix it, and then move on.
The Easterners definition of Fate is the possibility to choose your own past, and your own future. This meaning that in a way, man can choose and create their own fate. I agree with this, because after what they said about Karma, it is clear to me that they believe that everything is because of man.
a possibility of this free choice of his own fate is not always available because of karma of all the civilization.
Here they say that Fate may not always be possible. I think because someone may want a certain fate, but because of their strong belief in Karma, Karma will get in the way of their Fate
