They are only capable to perceive according to the limits of their brain. But their brains are not allowed to pass through the walls of the narrow room, for their consciousness operates only in that space. This narrow room can be a village, a political, a religious community, an ethnicity, or whatever. Such communities sooner or later will have their emblematic leaders who explain them that this community is the world itself. Whoever remains outside is the enemy of this world. Ideologies are formed and the fundamental principles are transformed. The doctrines are oriented in a particular direction. This is the case with everything that comes into human hands. Because man cannot tolerate if he/she is a subordinate being. He/she doesn't even tolerate to be on the same level with others. Somehow, he/she always wants to outdo and subjugate the other. He/she wants to control fellow humans, environment, nature. But since his brain was trained only within the walls of a room, as soon as he transcends the boundaries of his brain, the world outside the walls will avenge his actions. Not just the world outside the walls is turning against him. If his thinking is incapable of renewal, he will only find companions within his own group, which will genetically cause inbreeding in his population and his views become outdated, too. Individual like that in the long run, are not able to adapt to the changes and will extinct.
We are like the spider weaving a web into which it will be trapped and finally destroyed. But there is no such spider. However, man is like that. By the sense of superiority, he/she becomes victim of his/her own accord. Even religion is submitted to this superiority. I consider temples, mosques, and holy places as houses of Satan because a pure-hearted mortal human enters them with love in his heart and comes out with hatred. He hates everyone who is different from him. If one day it will be the other way around, my opinion will change as well. Let's see what the Quran says about this:

And they say: "The Fire shall not touch us but for a few numbered days:" Say: "Have ye taken a promise from Allah, for He never breaks His promise? or is it that ye say of Allah what ye do not know?" (Quran 2:80)

Say: "If the last Home, with Allah, be for you specially, and not for anyone else, then seek ye for death, if ye are sincere." (Quran 2:94)

So, if the Lord has chosen you, come on! Hurry up to die in order to meet Him as soon as possible. This aya was about Jews in Medina, but it is valid in every time. It's about us today, too.
Unfortunately, there are some Islamic orators who take this seriously, and send believers to death, but they forget themselves. But before anyone thinks that I am specifically criticizing Muslims, he/she is wrong. What I am writing about is a general human attitude that Muslims are not free from. Regarding Muslims, my only problem is using Islam as a mean for exercising their supremacy, whereas Quran teaches the opposite. Not only Muslims are like this, but everyone who work with principles or theories.
I recall an Indian story of a wise man who was sitting under a tree in a ragged robe with a small pot in his hands and lived as a beggar. When he was asked about the things of the world, he had always a good answer, guidance. His fame was spread far until the Maharaja became aware of him. He visited the wise man with an ornate entourage and spoke to him. The Maharaja was convinced that this wise man was not an ordinary man so he gave him an offer. He invited him to his palace to be his counselor minister. The wise man accepted it, but he had one condition. He asked for a room in the palace that no one else can enter except him. However, if anyone enters the room, he will leave the palace and the service of the Maharaja. They agreed and the wise man received the room and the Maharaja got the good advices. The wise man spent an hour alone in the room each day, but people could only see him going in and out. Nobody knew what was going on in the room. It went on like this for a while, until a rumor had started what could be in the room. Is the wise man hiding something there? Is there an enemy there? People of the palace couldn't wait long like that and one day they opened the room. Finally, they found the room empty. Only the wise man former ragged robe hung in one corner and the beggar's pot. After a while, the wise man appeared. He saw the multitude and the Maharaja among them. The wise man then knew he had to say something to the ignorant crowd so he started. In order to give you good advices, I need to liberate myself of your artificial world and return with my meditations under the tree where I was a beggar. I put on the beggar's robe and take the pot in my hand then the narrow world of your palace expands in front of me and I enter the space where the beggar can enter but you never. In that dimension, I can get answers to many questions that you won't. Because you have broken your word, I will leave you.

Among the decision-makers of today many would have to go back under the tree begging in order to make changes in this world. I know this is impossible. But the number of beggars is increasing. My goal is not to change decision makers, but to make beggars to see more clearly.
