We hurt ourselves when we collapse the walls around ourselves, and we know that the walls will cripple us, but something very much pulls us to destroy all the walls.
We kill ourselves when we destroy others. When we destroy ourselves for others. And in general, the world keeps on destroying one for the sake of the other, and so, along the chain, and in this chain there is a place for us, for everyone.
There is no good as such, and even one who has done good to you one day is not absolute good in relation to all and in all situations. You need to know this world a little deeper to be able to read it, as a textbook on philosophy. In order not to be emotional and malleable, to remain a pure emotionless consciousness.
You start to treat everything with too much responsibility and globally. If I eat meat, I'm a partner in the murder and I encourage it. If I give birth to a child, I can hurt him and improper education can grow from him an unexpected (unsuitable) person.
We are too closely connected and together we have created what this world is filled with. And if it rolls down, then it's time to clean your mind and subconscious, it's time to forgive and ask for forgiveness, but only if you realize that you are ready for it and that it's sincere.
