Religions and What means to be religious?

To start with, I should like to define what is religion. Literally it means "connexion" with something "supreme", with that which somehow transcends this world. Thus a religious man is that who is not of this world in a certain sense.
Now what we generally mean by religion? For most of us religion and belief are synonyms. "I am religious" means "I believe in some things". Thus it is with all religions: Christians believe in Gospel, God and Christ, Muslims -- in Koran, Hindoos -- in Upanishads. Some people, esp. some Buddhists and Hindoos say they don't believe in books, but they believe in practice, they believe in the things their teachers, gurus say. It is impossible to practice without belief that it is profitable -- every practice demand belief, esp. so-called religious practice because those teachers say themselves that it requires a great deal of patience, discipline and oppression of desires. Thus all those teachings demand some sort of belief.
Can belief be not of this world? To understand this we are to understand how we choose things to believe in, how we choose our guru, our sacred text. Obviously, we do this according to our prejudices and preconceptions, do we not? Why do I believe in the bible and not in the Tripitaka? Because my parents did this, because I am taught to respect the bible etc. But many people would say: "We are not so stupid to believe in the things just because our parents did this. We changed our religion. Now we are Buddhists though born in Christianity, or Christian though born in Buddhism". But a more perspicacious wit will notice that when we come to a new guru we choose him according to a certain criterion, do we not? And that criterion is irrational, it was instiled in us in childhood, in the conditions we lived in. I have chosen a guru because he has respectable features, because he can sit in meditation 9 hours etc. But the problem is how that criterion appeared. When we look upon it attentively, we shall see that it has its root in that very Pavlovian conditioning our environment performed, because we are taught to connect the word "good" with some attributes, which is caused by some sort of violence and desire.
Thus we can see that belief surely is not the link us and God, that it only connects us with the violence people made against us.
So what means to be religious? It doesn't mean that I believe in something, it means that I have nothing in this world to cling to, either noble, or ignoble. Religion is not a set of dogmas we agree with, religion is the state of an individual that understood the world and thus became free thereof. Religion is a great joy because it is freedom, it happens when one sees that he has nowhere to run, nothing to seek, when the ignorance stops producing new and new desires. When we understand that there is nothing worthwhile in this world that can be attained through our actions, we become psychologically free from the world. And this transcendence of the world is Religion.
