This state of weightlessness - for the person who has become accustomed to the gravity of the Earth - is a very difficult and frightening state to be put in. Thus, they must be trained in a man-made weight-less environment so that when they are put face to face in such an environment in space, they are not dazed - rather, they are able to accomplish their goals.

These astronauts are placed in a specially designed chamber and are continuously moved up and down - of course in such a way that would not lead tp any broken bones - and after coming out of this enclosed chamber, the face, head and feet of some these astronauts are sometimes bloody (due to minor injuries). No matter how much they try and take care to protect themselves, this free falling is not something that a person can come out of easily with no scratches to his body.

This sensation of weightlessness can be experienced on Earth when a person is free-falling - such as when a person falls from a high place down to the ground. For those few seconds that he is in the air, he will experience what it means to be weightless - the same feeling that the astronauts feel! If we consider the journey that astronauts take, we see that it requires a lot of preparation (on their part) accompanied by difficulties and struggles.

Just imagine what is required for the greatest trip - the one towards the next life! How much must a person prepare for that trip and how many difficulties one has to go through and what sort of things must one's soul struggle to fight against so that one would be able to reach that great and exalted status of the next life!

Is it possible that without any struggles or difficulties and by not tasting the pain of inconvenience and of bereavement, one can reach to any station or rank (in the next world)?!

There are many people, who in order to reach higher levels and ranks with the military, go through difficult exercises and training and force themselves to experience the pangs of hunger and thirst such that sometimes they go for long periods of time with only water to train the body: نابرده رنج گنج ميسّر نمى شود مزد آن گرفت جان برادر كه كار كرد “It is not possible to gain the prize without going through difficulties, The one who went through troubles is the one who will get the reward.” It is here that we must stop and think - What have we done in this world?
