Flying is an art, or more precisely, a skill.
The whole focus is to learn how to swipe your body into the earth’s surface and miss it.
Try to do this on a good day, the “Guide” recommends.
The first stage is simple.
One thing is required of you – to rush down firmly without fear of the physical pain that awaits you.
That is, it will hurt if you can’t get past the ground.
Most people fail, and the more effort they put in, the greater the likelihood of a collision with the ground. Of course, all the difficulty in the second phase is in failure.
The main thing is to get past the ground by chance. There is no point in trying specifically to fly by, because it is simply impossible. No, the whole thing is that in the middle of the road to the earth you have to get distracted by something, forgetting both the prospect of falling, and the ground, and how you will hurt if you can't miss.
